Hi Steve, I'm not sure which kernel, specifically, you want tested from proposed. but I tested 2.6.32-24.38 (amd64) and I'm still seeing freezes. (I find ripping a DVD in handbrake is the easiest way to force a freeze in only a few minutes, but I still get freezes randomly without it).

[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
All, please note from the earlier posts florianr, myself, and others confirmed that the freezing we were seeing could still happen without X and the desktop running, and on very different video hardware. If your bug seems to be graphics related, you should probably report it separately. I can confirm that I'm still seeing freezes under the latest lucid 2.6.32-23-generic and 2.6.32-23-preempt. Further testing shows that if I boot with kernel parameters noapic nolapic then the freezing does not happen. I'm currently writing this while playing 720p video, ripping a DVD in Handbrake, recording an HD video in mythtv, commercial flagging a program, running virtualbox (busy doing a virus scan) and playing audio in amarok. While the system is pausing occasionally under the CPU/disk/memory load no freeze. A torture test that would be sure to freeze in a few seconds if I ran without noapic nolapic. Further, if I boot with kernel parameter noacpi I still have freezes it has no effect on it's own. Again, this is a regression from karmic where I could run without noapic nolapic. -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
The suggestion of using 2.6.31-10-rt prompted me to give 2.6.32-22-preempt a try. While I was impressed with how responsive the desktop seemed with a mix of high CPU load tasks going on in the background, it still failed the torture test and locked up this time with the return of both the do_IRQ: 0.177 No irq handler for vector (irq -1) and BUG: soft lockup - CPU#1 stuck for 61s! [ghb:9719] just before the freeze. The system was a little more responsive while it was freezing... I was even able to switch desktops and try other apps. Firefox, Handbrake and System Monitor locked up right away (grey windows) - I'm guessing they were on CPU 1, the one which experienced the soft lockup. The desktop CPU load widget showed CPU 1 at 100% Other apps. seemed okay briefly but ultimately everything locked solid within a couple of minutes, although I was able to reboot with SysRq+REISUB. I did get quite a lot of info in kern.log this time... the fun starts at line 1003. I'll give 2.6.31-10-rt a try in the next couple of days. ** Attachment added: kern.log http://launchpadlibrarian.net/49801638/kern.log -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
Just so we don't get too many unrelated freezes being tracked in this thread... the symptoms characterized by florianr were: - issue was NOT present prior to 10.04 - intermittent system-wide freezes - frozen image on screen, showing the desktop image without any change and not taking mouse/keyboard actions - sometimes MagicSysRQ (R-E-I-S-U-B) works, sometimes not. - system log is still active for some time after the freeze appears to happen - system logs do not contain any obvious/consistent message that identify the cause of the freeze - issue is STILL present testing with upstream kernels (except that you may be able to continue moving the mouse or a period of time) - not a memory issue - system stays connected via wireless (if using wireless) - issue appears on very different hardware (intel CPU and. AMD,; intel video and nVidia), - not related to a specific desktop (gnome and kde) or a specific application (e.g. virtualbox, firefox, etc.) From my own observations: - a freeze can be provoked by running processes with high CPU (and possibly disk I/O) such as with handbrake - I've been able to prompt freezes with no desktop or X server running although I don't know if florianr can confirm this on his system. As such, I doubt the problem can be compiz or xorg related (although, note that it may be processor load related, as as such something like compositing could make a system more likely to freeze) - I can eliminate freezes by booting with kernel parameters noapic nolapic acpi=off florianr, so we can see whether we're still dealing with the same bug or not, could you please verify: - your system still responds to pings when frozen (and you can't ssh in) - your system doesn't freeze if you boot with kernel parameters noapic nolapic acpi=off Others, if your symptoms are different from those above, you may want to start a new bug report. -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
I had 3 freezes yesterday. In each case the last entry in kern.log was: do_IRQ: 0.189 No irq handler for vector (irq -1) (Sometimes the number is 0.175, 0.177). (Interestingly, there have been no instances of the BUG: CPU soft lockup messages in the last two days. I ran a memory test overnight and it was clean. I also tested kernel 2.6.31-02063112-generic, 2.6.34-020634-generic, 2.6.35-020635rc1-generic today. All of these froze. In exasperation, I booted this morning with noapic nolapic acpi=off on the grub kernel parameters with current 2.6.32-22-generic. This disables all power management (as I understand it), such that my system is running full-out all the time. The system has been running solid ever since. Even with torture testing it with a DVD rip in Handbrake, Virtualbox, MythTV recording and commercial flagging, an h264 transcode, and Amarok playing all running simultaneously. The DVD rip alone would have been enough to lock the system up within a few minutes without noapic nolapic acpi=off. This is not desirable work-around, or a long-term solution, but it at least lets me work for the moment, and allows me to continue helping debug rather than reverting back to karmic. To re-iterated: this system has been working fine for over a year with karmic and jaunty, with power management. This is a regression with Lucid, and the issue is present with upstream kernels as well. It would be very nice if someone could assign a more appropriate High Priority to this issue and we could get some attention from some devs before this bug report becomes a confused with too many un-related freezes. -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
I had a freeze during the night, with the last message that was written kern.log: Jun 3 01:21:47 family kernel: [13403.676449] do_IRQ: 0.177 No irq handler for vector (irq -1) Examining the log more closely, I've had four freezes in the last 24 hours... in each case, there are between 1 and 4 incidents of No irq handler for vector (irq -1) in the log just before the freeze. In one case, the message was followed by the CPU soft lockup message just before the freeze. However, there are a few incidents of No irq handler for vector (irq -1) which did not result in a freeze. And, I've had freezes just after the the CPU soft lockup message, where the No irq handler message didn't appear. So, while neither No irq handler nor the CPU soft lockup message may be the smoking gun, there is at least the stench of gunpowder nearby. This is back on the current lucid kernel 2.6.32-22-generic. ** Attachment added: kern.log http://launchpadlibrarian.net/49610911/kern.log -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
Priority should be at least high. I experienced over a dozen crashes last night, as I tried various kernels. Finally my system wouldn't boot anymore - just a grub prompt, and no menu. (I think, because the system froze while I was installing an old kernel/headers.) Took me about 3 hours to figure out how to get it working again (complicated by my booting from software RAID, and by the fact that for some reason grub2 was never installed, and there was no grub menu on either boot disk). Apart from the hours/days of lost time, now I'm quite nervous about losing data as well. I want to help improve the distribution, but I need a stable system will probably have to revert to karmic on the weekend. -- Ubuntu 10.04 random freezes https://bugs.launchpad.net/bugs/585765 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I've had the same behaviour while playing audio... a few seconds of audio playing over and over again, and no other response from the system (except possibly ping...didn't check that when it happened.) If it's related to disk I/O... I boot from a RAID-1 EXT4 root file system, assembled from 2 x 1TB SATA II drives.

[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
Okay, some progress. I was on a screen showing the System Monitor and some processor load widgets when I experienced my most recent freeze. The System Monitor window went blank, but I could still move the mouse, and I could the processor load widgets kept running I could see that both cores had gone solidly to 100%. I clicked on the desktop icon for konsole about 5 minutes later, I got a pop up message saying that the application couldn't be started. I let the system continue to run for almost 20 minutes... the mouse and keyboard froze, however the system still responded quickly to external pings, and there was regular flashing of the disk activity light which I believe was from an HD- PVR recording to a separate drive that was in progress at the time of the freeze. So, it's not a real freeze... something is stealing 100% CPU time, such that you can't even toggle numlock on the keyboard. The kernel is still alive responding to networking pings, and the HD-PVR driver is still taking data from USB and storing it to disk. So, I started hunting logs from the time of the freeze. The attached kern.log shows what happened during that very busy period. The following message seems to have been the start my systems flash forward ;-) more info in the log.

Me again. ;-) Checking my old logs further, I found 92 incidents of BUG: soft lockup from a variety of processes (kswapd, soffice.bin, mythbackend, firefox-bin, soffice.bin). In each case, the CPU (sometimes CPU#0, sometimes CPU#1... I only have two cores) is stuck for a reported 61s.

I removed virtualbox-3.2 just to eliminate outside code from the kernel, and because I saw a higher frequency of freezes with virtualbox running. System still froze with virtualbox removed. Also tried going back to 2.6.32-21-generic, and still had the freezes. Three freezes so far today, with the system lightly loaded.

Hi Florian, I agree, my bug (586901) is a duplicate of yours - thanks for catching it. However, I would say kai's problem in the above comments is different, as I've never been able to ssh in after a freeze, and I gather you haven't either. I see the exact same behaviour as you under the upstream kernel freezes where I can still move the mouse, but otherwise the same. Hard for me to see it being graphics related, as I can still experiences freezes from a text console with X shut down (but with the system still under heavy load.)
