[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically due to internal alsa-plugins pulse check
@Jens -- whatever DNS server you are using while connected to VPN probably doesn't quickly return an answer for a query for "localhost," while your non-VPN DNS does. alsa-utils 1.0.17-0ubuntu3 should avoid it in all cases. Also, see below. @kungmidas -- when I change my DNS to some bogus address, I see this delay. When I use good DNS servers, the delay is gone. alsa-utils 1.0.17-0ubuntu3 should avoid it in all cases. Also, see below. @all, please see https://bugs.launchpad.net/ubuntu/+source/network- manager/+bug/274995/comments/273 -- if you were seeing a delay -- even if it is fixed now, you probably also have or had that separate network configuration bug 301430 that allows DNS queries for localhost -- however generated -- to escape your local machine and network. -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically due to internal alsa-plugins pulse check https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Public bug reported: Binary package hint: snort package snort 2.7.0-19ubuntu1 failed to be uninstalled: subprocess pre- removal script returned error exit status 123 This report was initiated by the crash-reporting process. I am adding the following information manually. Used Synaptic Package Manager to install snort and, after dependencies, 5 packages were selected. After install, I ran snort a couple of times (it didn't seem to start, gave me the message "you've got to tell me to do something" (both without sudo and with, and I don't know what I'm doing so my command line arguments were probably incomplete).

I am attaching a second "Screenshot - Synaptic Package Manager console window following error message" which is the scrolled-down view. I also notice that there seems to be some DpkgTerminalLog.txt info from a previous session, but today's information also appears toward the bottom of that log. SEVERITY/PRIORITY SUGGESTION - Unless further investigations see deeper impacts than are apparent to me, I suggest that this is not a critical- priority bug as the exception appears to be detected, and when coupled with Synaptic Package Manager, it is logically handled following rather intuitive steps (simply try again). However, it is also not "Low" as the error messages are neither user-friendly ("Error 123") and appear "scary" (big-red "Stop" indicator, Crash Detector appears in Gnome). HTH & good luck! ** Attachment added: "Screenshot - Synaptic Package Manager console window following error message -- scrolled down" http://launchpadlibrarian.net/20323674/synaptic-console2.png -- package snort 2.7.0-19ubuntu1 failed to be uninstalled: subprocess pre-removal script returned error exit status 123 https://bugs.launchpad.net/bugs/306567 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you Antonio. That helps assure me that the results I'm seeing apply to the patch. As also reported above, I now can't shutdown cleanly without hitting the wifi switch.

Tom, I got the kern.log entry mentioned at https://bugs.launchpad.net/ubuntu/intrepid/+source/linux/+bug/276990/comments/92 which is the patched (comment 85) behavior of that bug. The news is that I didn't use that patch, I used the patch from comment 52 in this bug.

[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up
Just a couple of notes on this. 1. For those with working ALSA sounds, but ALSA hangs on shutdowns lasting about 2.5 minutes, I believe our bug fix is mentioned http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.5 -- released November 7th. (I don't know how soon we will see it through normal channels -- can anyone advise?) commit a858c06703057cfdd142184e536c3ba36c45000e Author: Takashi Iwai <[EMAIL PROTECTED]> Date: Thu Oct 30 19:10:15 2008 + ALSA: hda - Add reboot notifier commit 0cbf00980f0fc4cc064a15ab3dfce19b5fae9130 upstream The current snd-hda-intel driver seems blocking the power-off on some devices like eeepc. Although this is likely a BIOS problem, we can add a workaround by disabling IRQ lines before power-off operation. This patch adds the reboot notifier to achieve it. The detailed problem description is found in bug#11889: http://bugme.linux-foundation.org/show_bug.cgi?id=11889 Tested-by: Luiz Fernando N. Capitulino <[EMAIL PROTECTED]> Signed-off-by: Takashi Iwai <[EMAIL PROTECTED]> Signed-off-by: Greg Kroah-Hartman <[EMAIL PROTECTED]> 2. It's possible that this bug report is a duplicate of bug#126140. I'm not sure. That would make this a very old bug. That reporter noted that doing an rmmod of snd_hda_intel prior to shutdown avoided the hang. A similar solution posted at http://bugzilla.kernel.org/show_bug.cgi?id=7195#c3 (status NEW for over 2 years) describes putting similar entries in a shutdown script. Another commenter at https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.22/+bug/126140/comments/38 says that using aggressive power saving mentioned http://www.thinkwiki.org/wiki/How_to_enable_AC97_power_saving#HDA_audio_subsystem softens the problem. More recently, many are reporting, especially on ubuntuforum, that doing an ifdown on their active network avoids this ALSA hang on shutdown -- https://bugs.launchpad.net/ubuntu/+source/alsa- utils/+bug/274995/comments/25 mentions it as well. That the workarounds are different makes me wonder whether these actually are duplicates.

Jakub, What was the date/time when the system locked up? You'll want to check your logs matching up those times to help figure out why the kernel panicked. As to the printout you provided, those look like routine firewall logs. To get help with turning that off, see http://www.ubuntu.com/support/communitysupport for different ways to get help.

[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up
I'll buy the beer if this is a BIOS bug. Bug 295136 (aschuring) is the most succinct test case I've seen on this. That bug is a duplicate but shows what is going on. It should not be ignored. Key observations: ---Quote--- After dist-upgrading to intrepid, Ubuntu appears to hang when shutting down. I have traced this down to the ALSA shutdown script taking more than a minute (!) to save sound card state. More specifically: [EMAIL PROTECTED]:~$ time amixer -c0 -q set Mic 0% mute real 0m8.061s user 0m0.003s sys 0m0.012s This is reproducable only in single-user mode. When I run the amixer command when logged in into X (I can even run the command from a console, as long as X is running), the same command takes only a few milliseconds as it should. I will attach an strace log from above call. Of interest is the following line: 4.013297 ioctl(5, FIONREAD, [37]) = 0 which occurs twice in the script. It seems to be expecting data from a network socket, but I can't figure out why. ---endQuote--- - commenting out everything in /usr/share/alsa/pulse.conf: amixer responds fast (The description of this file is, "PulseAudio alsa plugin configuration file to set the pulseaudio plugin as default output for applications using alsa when pulseaudio is running." However, pulseaudio is not running, wasn't running, so why does Aschuring's commenting out of lines change anything? /usr/share/alsa/pulse.conf calls its config from /usr/share/alsa/pulse-alsa.conf which appears to set pulse as the default sound device.

@Luke, My quick test -- There was the same hang with your new file as written (without the variable being exported).

Edit /etc/resolv.conf and change your working nameserver line to one with an unoccupied IP before shutting down and rebooting, for example 192.168.0.177, and the DNS query being generated will go to a address that will timeout instead of to your nameserver.

All, If you are or were experiencing this delay, there is a related bug report -- bug 301430 -- concerning the omission of localhost in the ipv6 part of /etc/hosts. While bug 274995 is fixed by the update to alsa- tools, the delay uncovered by bug 274995 was only experienced by those of us who had bug 301430 as well. Bug 301430 is marked as "incomplete" and will expire unfixed without confirmation that it affects others. I suspect that everyone who noticed a delay during shutdown owing to 274995 also has an IPv6 misconfiguration in the /etc/hosts file, even if they're not using IPv6 and even if the delay is now fixed. Please help out, check, and advise. WHAT YOU SHOULD DO: 1. Even if the latest alsa-tools update fixed your problem, please check your /etc/hosts and verify whether or not it was set up correctly. A CORRECTLY configured file originally had (or has) this line (the whitespace-separated word localhost is included among the hostnames in the ipv6 section of /etc/hosts): ::1 localhost ip6-localhost ip6-loopback An INCORRECTLY configured file had or has this line (the whitespace-separated word localhost is NOT included among the hostnames): ::1 ip6-localhost ip6-loopback 2. If your system was or is INCORRECTLY configured, please visit bug 301430 and indicate so via a comment. The /etc/hosts file is created as part of the network installation and configuration.

[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up
Even though they have a lot in common, I'm convinced these issues have two different root causes, but I'm also hopeful that the change for bug 126140 will also avoid ours (bug 274995). Bug 126140 is about certain PCs that remain powered up at the end of their shutdown sequence. Anyone remember the Windows "It is now safe to turn off your computer" screen? That's essentially the behavior of bug 126140, minus the cheery-souding Microsoft comforting. Both that problem and ours ... can be avoided by rmmod -f snd_hda_intel (the sound driver) ... generally involved Alsa ... interrupted normal shutdown But ... 274995 is not actually a hang ... 126140 actually is a hang ... 274995 has a networking workaround ... 126140 seems to have a power-management workaround The "fix" for bug 126140 isn't r-e-a-l-l-y a fix because it doesn't address the root cause (which certainly could be a BIOS oddness), but it does avoid it. Before the hang, the code will now respond to a system reboot signal by releasing the interrupts. It was tested against the problem in 126140. If the net effect of releasing the interrupts is the same as "rmmod -f snd_hda_intel" then it should also avoid our problem as well. We should test it. If it does, we should also make sure that nothing else broke in the process -- for example, does the shutdown in /etc/init.d/alsa-tools still save and zero mixer settings like it was written to do? My suggestion is that we don't call these duplicate bugs until such testing is complete, even though we are hopeful that this one change avoids both issues. -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up
Thanks for agreeing with me, aschuring. :-) However, the change for 126140 certainly won't benefit you so my previous advice of "wait and hope" no longer makes sense for some. This is a cascade of bugs and behaviors. In bug 295136, FlagMan said, "If pulseaudio is the default sound sink and you are NOT logged into X, amixer will search the pulseaudio server but there is none running on the local machine. Therefore, the network will be searched for a pulseaudio server. Most likely there is none on the local network either, and network timeouts are set to high values, so this may take some time and is the symptom we are seeing." MY THEORY (and I'm not too strong on my capture of linux sound, so beware): I think the root cause is in that first sentence -- the user is no longer logged into X, the pulseaudio daemon has been terminated when the user session ended, but pulseaudio is still sought by alsa tools. So amixer, searches fruitlessly for the daemon and it has to wait for a network timeout every time its called, and it is called numerous times in /etc/init.d/alsa-tools as the script zeros and mutes channels. (After the user logs out of gnome, I have also noticed a delay between the time that "gdm" appears ready for input and /usr/share/sounds/question.wav plays, which is played by gdmplay which is simply a script that calls aplay, another alsa tool trying to do something after pulseaudio has ended.) Finally, gdm.conf has this text, ---Quote--- # Program used to play sounds. Should not require any 'daemon' or anything # like that as it will be run when no one is logged in yet. SoundProgram=/usr/lib/gdmplay" ---EndQuote--- This points the finger at alsa-tools OR, and I think this more likely, the ubuntu user-session implementation of pulseaudio, and here's where my lack of knowledge about these ends my usefulness -- I don't know the implications of default sinks and whether the closing gnome session can and ought to switch audio defaults back and forth. It should be noted that pulse's xsmp module is installed to load upon login, and never does. That might have everything to do with this. It is probably not a bug that the alsa tools looks for pulseaudio using network calls. This is not only very common, it works fine when the network isn't searching DNS for the localhost hostname. Even though many workarounds involve killing the network, or nfs, or uninstalling pulseaudio -- these are avoiding the symptom. There might be a bug related to whether alsa tools seeks the network correctly, and how to do that in IPv4/IPv6 LAN has been the topic of much disagreement (see below). SECONDARY ISSUES: It was found that listing localhost to :::1 in the IPv6 section of /etc/hosts avoided the long delay mentioned in this report. Some distributions, including Debian, include (or have included) that entry in /etc/hosts by default while others have not (including Ubuntu, apparently, starting with Hardy (bug 211537). However, and this is important no matter which way this goes, several VERY POPULAR network applications that have bug reports indicating that they fail or misbehave when localhost is listed twice in /etc/hosts (these reports are older and are probably fixed). How to handle localhost in lookups as everyone transitions to IPv6 has been the source of questions http://lists.debian.org/debian-ipv6/2008/07/msg0.html and heated (and infamous) discussions http://sources.redhat.com/bugzilla/show_bug.cgi?id=4980 and contradiction http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=427067 (seems to indicate that localhost ought to be listed in the IPv6 section, even though it means that localhost is listed twice). I have researched this question for days and can't find which answer is right. However, as a result of this bug, and as observed by aschuring, my system ends up sending DNS lookups for localhost to the WAN. However, even though localhost lookups for IPv6 might be a bug, fixing it only hides the fact that pulseaudio is not running when the alsa tools need to find it (the root cause bug). It seems like when the user logs out and the pulseaudio daemon is not running, alsa tools should stop trying to find it. -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am going to try and change the "invalid" status for pulseaudio and alsa-tools. alsa-tools, pulseaudio -- please re-evaluate.

[Bug 274995] Re: MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up
@Dove, It's probable that everyone who uses pulseaudio as installed by Intrepid will experience this bug. The question is whether or not they'll experience the long hang that helps us notice it -- and that is determined by the networking configuration. It appears to me that users who once had an IPV4-only system and upgraded will avoid the wait for timeout caused by the bug (the alsa- tools still look for the pulseaudio server, but fails to find it much faster). This is because the upgrade script notices the ipv6 section is missing in /etc/hosts and installs one including the "localhost" name in the ::1 line. Users who manually add the "localhost" hostname to the ::1 line in /etc/hosts also avoid this wait. My guess is that users who disable IPV6 after installing will also avoid this wait for timeout.

Hi Dov, I'm glad you posted. It seems I've made the bug Gods angry -- it won't show itself on my system tonight, and I can't figure out why. I hate when that happens. > I tried killing pulseaudio while logged in to an X session, and it still hung while shutting down. Right. Killing pulseaudio while logged in should show the same problem when the gnome user hits reboot or shutdown. The pulseaudio daemon gets killed then the alsa utility tries to contact it. That is the crux of the issue -- should alsa be trying to contact the pulseaudio server after its killed? Or, should something in the sound configuration revert before pulseaudio gets killed so that the alsa tools don't try to contact the pulseaudio server? I don't understand the architecture well enough to know for certain. The freeze (~ 15 seconds each for 7-10 times that amixer is called to zero and mute the mixer in /etc/init.d/alsa-tools stop) occurs as amixer waits for a DNS query to time out. If the pulseaudio server is alive, the DNS query doesn't happen. If the pulseaudio server is unexpectedly gone, then amixer searches localhost for it. Since it's not found on ipv4 and ipv6 doesn't have localhost in /etc/hosts, the query goes to the WAN and things pause for 15 seconds while amixer waits for a reply. -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
