[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes
Recently several people mentioned to stop using Ubuntu 10.04 and start using other distributions. I mentioned in # 47 and # 71 of this thread that I plan to do the same. I have now 7 distributions on two machines. HP desktop , AMD 5600+ with : Fedora 13, OpenSuse 11.2, Gentoo (and Windows Vista on another disk) Fedora 13 and Gentoo both fail occasionally caused by freezing of keyboard and mouse (once a week at most ) OpenSuse 11.2 seems very stable (seen only once).Note I can live with the failure frequencies. I choose for Fedora and OpenSuse 11.2 as my default system for my work. HP laptop (8 years old with one Intel processor) : OpenSuse 11.3, PCLinuxOS (pretty neat BTW), Mandriva 2010,1 and Debian I have limited statistics on keyboard failure, but it is rare. I did not notice any failure on Debian yet (running a 2.6.26 kernel !?). Note I am using a mix of nvidia (Gentoo only) and standard Xorg drivers for the graphics dependent on distribution Of course this does not prove anything, but failure rate on other distributions than Ubuntu are rare from my perspective. Although I am convinced the basic bug is an issue around the kernel 2.6.32 and later (I see it on all distributions apart from Debian, Ubuntu failed also without graphics-Xorg), there must be a variable in the Ubuntu distribution on top of the kernel and Xorg which makes Ubuntu unworkable for me on the AMD machine due to the failure rate Note, I tried to install Ubuntu on the laptop using a LiveCD disc (nothing wrong with the CD, checked and rechecked). That failed too, it failed during booting of LiveCD (old hardware?), and yes indeed keyboard hangs too (including REISBUD interupts) ;-( -- 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 was able to reconfigure my HP desktop from scratch with 4 concurrent OS after visiting my hardware supplier|: Windows Vista on one disk and different Linux brands on the other disk with: 1) OpenSuse 11.2 with kernel: 2.3.31 and a Gnome like (Xorg ?) 2) Fedora 13 with kernel: 2.6.33.5 (gnome) (Xorg nouveau) 3) Gentoo with kernel 2.6.32.-r7 (kde) (nvidia) The HP had no crash or freezing problem using any of the OS so far. Previously I mentioned I had crashes with Ubuntu lucid (2.6.32:22) with and without nvidia for the GUI and even without a Gui driver like Xorg and/or nvidia. Not able to ping the system after freezing. REISBUD failed too. I noticed that the problems became more severe after introduction of 2.6.32:22 kernel. The gentoo kernel 2.6.32.7 I am using at this moment is stable so far. So probably not a pure kernel problem I stated before in entries of thisbug that perhaps power management and/heating could be the problem looking at the behaviour of my HP refusing to boot immediately after resetting (too hot to pass the bios?!). Of course other programs/utilities installed when 2.6.32:22 was introduced and perhaps using 99.9-100 % of the CPU, could be another explanation of the the random freezes. To judge that I leave it to the team responsible for integration testing of ubuntu I can understand that although we have more more than 48 pages of complaints and tests on Ubuntu forum (is that a historical record?) http://ubuntuforums.org/showthread.php?t=1478787page=48 and more than 70 entries on this bug report, it is not clear what the problem is. To set the status to incomplete for this bug report, I can understand from a software maintenance point of view. There is no clarity at all what is really the bug. As usual the define the correct and complete bug report is already more than 75 % of its solution. To define a proper (integrating) testing plan may help too to isolate the bug(s) Regarding the current release , it is better to define it as a pre-alpha one. Perhaps I may return to use Ubuntu again when 11.x has been released and is operational for a couple of month. Ubuntu is not my default OS any more. -- 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 mentioned in a previous entry (#43), my HP desktop needed a check-up by my hardware consultant due to the many hard resets. Currently, the machine runs on its original OS Windows Vista without any problem and without any replacements needed. Discussing the issue with this consultant and others, we noticed that a problem with the heat control could explain the behaviour observed. (so ACPI). Running the program SpeedFan on Vista did not show a problem, however. So Vista is better than Linux for my HP (oops, never thought I would be able to write that down) It could be a wild speculation, but I am suspicious about the transition from kernel 2.6.31 and 2,6.32 regarding the ACPI code of the kernel. I have the following arguments: a) booting with acpi=off helps as mentioned a.o. by databubble (see item #39) b) There is a variety of failures mentioned by different people, (with or without mouse, keyboard, wireless , heavy graphics load, etc etc). The different computers, different hardware configurations could explain why this variety is occurring, but heat problems may explain the failures of peripherals and kernel. c) Still looking into the changes made, but apparently a lot has been changed with the introduction of 2.6.32 regarding power control and speedup during booting. Regression testing not rigorously enough for all hardware? For the record my computer is a HP m8000, without ability to control the ACPI on the bios (setting S1 or S3 for instance). I cannot afford to install Ubuntu Lucid with 2.6.32 at this moment, I will install a Linux (OpenSuse, Mandriva, Ubuntu 9.10) with 2.6.31 or even older kernel. -- 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
Unfortunately the many hard resets needed to reboot my multiple-linux AMD hardware (all 64 bits) (Ubuntu Lucid,gentoo, gentoo ~amd, Fedora 12, OpenSuse 11.2,Mandriva, Debian) resulted that my bios failed, and a check-up is now ongoing by a hardware specialist,;-))) So no detailed reports are available, only a couple of observations. 1) Linux versions with older kernels (pre 2.6.32) did not freeze like mandriva, OpenSuse, Fedora 2) Gentoo and Ubuntu had regular freeze of keyboard mouse (both USB) and screen (2.6.32), 2.6.32/33/34 for Gentoo) 3) Observations made by databubble (item #39 of this thread) correspond to my experiences However: a) No special activity was required to get a freeze b) Often freezing happened after some idle time (no human interaction with keyboard or mouse) c) wireless (atheron ath5 driver) failed too. Pinging Ubuntu machine from my windows machine did not work after freezing d) REISUB never worked (keyboard always dead) (e.g. caps lock also dead) e) freezing occurs also when X was not running (!!!) (So no relation with Xorg and/or Nvidia ?) f) After upgrading from Ubuntu 9.10, the freezing did not happen in the early days. Some indication when 2.6.32:22 was installed the problem were appearing, at least a high frequency seen after 2.6.32:22 and only rare before 2.6.32:22. A similar observation is valid (so far I remember) for the early versions of gentoo-2.6.32 kernels. -- 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
