Tim - You presume correctly.

I'm running on hardware very similar to that of the original bug report.

order to do that please install the current Natty kernel from

proposed?field.series_filter=natty . I suggest just copying the deb and
installing directly ('cause its easier to remove afterwards):

May I just add - as mentioned in one of my posts above, the commit just preceding the one I bisected this bug to may be related, as on the system where this bug occurs there are some very short (quarter to half a second?) freezes in cases when this bug occurs, instead of a hard freeze, which disappear when that commit is removed. Both of those commits modify page allocator (I can find that commit's sha-1 if needed, but it directly precedes this one). I can also report another bug for it if needed, but it may be wiser to simply have a look at both of the commits. I don't have any experience in kernel development so I may of course be mistaken as to the role of preceding commit. Also, my way of reproducing this bug, which seemed to work every time: 1. On an affected system, run Open Office, GIMP, Inkscape or any other memory-hogging application. 2.

Hi Pawel, Been running your custom 2.6.35-28 for a few days, no freezes. So in my opinion he patch you bisected out is probably my culprit as well as yours. Headers compiled okay as well.

Kernel compilation produces a lot of warnings and it's ok, as long as it gives you a 'final product' in the form of .deb packages.

Looks like the effects of apt being interrupted while it was doing something before. It shouldn't matter for kernel compilation, but you may want to uninstall and reinstall VirtualBox at some point (which should fix the error). You do need the build-dep linux though, so if the error occured before the installation finished, then there's a (very small) chance that you can get some really weird errors when you attempt to compile the kernel if you don't fix it. The first two warnings from update-rc.d don't really mean anything bad, it apparently is a configuration bug in Ubuntu ( https://bugs.launchpad.net/ubuntu/+source/kexec-tools/+bug/569980 ) - kdump is used to create kernel crashdumps and all this is saying is that they will only be created during 'normal operation' (runlevel 2) rather than also during startup, shutdown, etc (which have different runlevels). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719446 Title: systematic freezes on any kernel version post 2.6.35-22 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Oh, and VirtualBox won't be enabled in kernel that you compile - you would need to create and install kernel headers for your git source for that; you can do this by running: fakeroot debian/rules binary-indep after building the kernel, which would give you linux-headers(...) package which you need to install so DKMS is able to auto-compile VirtualBox kernel module. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719446 Title: systematic freezes on any kernel version post 2.6.35-22 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, so this commit is related to this bug (after bisection): 58e15f5029c75b45adbcb25cd76a36d26a6c4297 is the first bad commit commit 58e15f5029c75b45adbcb25cd76a36d26a6c4297 Author: Christoph Lameter c...@linux.com Date: Thu Sep 9 16:38:17 2010 -0700 mm: page allocator: calculate a better estimate of NR_FREE_PAGES when memory is low and kswapd is awake commit aa45484031ddee09b06350ab8528bfe5b2c76d1c upstream. Ordinarily watermark checks are based on the vmstat NR_FREE_PAGES as it is cheaper than scanning a number of lists. To avoid synchronization overhead, counter deltas are maintained on a per-cpu basis and drained both periodically and when the delta is above a threshold. On large CPU systems, the difference between the estimated and real value of NR_FREE_PAGES can be very high. If NR_FREE_PAGES is much higher than number of real free page in buddy, the VM can allocate pages below min watermark, at worst reducing the real number of pages to zero. Even if the OOM killer kills some victim for freeing memory, it may not free memory if the exit path requires a new page resulting in livelock. This patch introduces a zone_page_state_snapshot() function (courtesy of Christoph) that takes a slightly more accurate view of an arbitrary vmstat counter. It is used to read NR_FREE_PAGES while kswapd is awake to avoid the watermark being accidentally broken. The estimate is not perfect and may result in cache line bounces but is expected to be lighter than the IPI calls necessary to continually drain the per-cpu counters while kswapd is awake.

I installed 2.6.38-999-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ and got ambiguous results. I got a freeze when copying sets of files of 600M+ in Nautilus, but only after a half dozen tries I wasn't able to get a freeze copying similar amounts using c -r in a console reached using ctrlaltf1, despite many tries.

Not very comfortable with trying latest development release, if there's a reasonable change it will screw up my existing installation: I don;t much fancy redoing everything I've done up til now. I don't yet have partition backup/mirroring set up, so I've got no way to easily undo any serious damage. Latest upstream kernel sounds a bit safer? Any use to you if I install it on my current Maverick installation (as opposed to latest dev release) and test? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719446 Title: systematic freezes on any kernel version post 2.6.35-22 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well, if you could get the exact text of that error it might help; I think the text I sent was it, barring the code; but I'll try to get that too using one of methods you suggested. Log files not available, so I'll try the other methods you suggest next week. ..snip. Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . Can I pick your brain on this? (But tell me to go away and google if that's best for you). As said in previous posts I'm pretty new to ubunu/linux. I'm trying to beat laptop into something that can do most of the things I do on my windows machines, which means running win versions in VirtualBox VMs for for forseeable future. In my experience VirtualBox is very sensitive to which kernel version (and presumably release) of ubuntu I'm using, and I've already got a slew of other software installed on my current version that may or may not work with latest release. So is best approach to install development release and kernel in a new partition, and multibooting? If I install development release I assume it will notice existing grub stuff and just add itself to existing grub menu? ..snip.. Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . I guess I want current version, pointed to as http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ ? I assume I apply that to existing Maverick install, not on? or also on? development release install?

[Bug 719446] Re: systematic freezes on any kernel version post 2.6.35-22
Hi Alan, Installing development versions in another partition is a good bet - however being a development version any type of hideous error might occur and destroy the other installation - that's what you get with development. http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ would probably be the right thing to try for the upstream; if you install that you should still be able to boot back to the old one.

Hi Alan, Thanks for that. Those errors shouldn't happen - so it's pretty likely a kernel bug. There are a few ways to get those messages; 1) If you're lucky they'll have been recorded in /var/log/kern.log or /var/log/kern.log.1 or /var/log/debug 2) A digital camera picture of the message is OK if possible. 3) If you're logged into a virtual console, say the one you get with ctrl-alt-f1 if you do cat /dev/vcs1 myfile it'll record the text contents of the screen into myfile.You can also do the same to the other console; e.g. if you're in ctrl-alt-f1 then you can cat /dev/vcs2 myfile to get the one from ctrl-alt-f2 Dave ** Changed in: linux (Ubuntu) Status: Incomplete = New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719446 Title: systematic freezes on any kernel version post 2.6.35-22 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well, if you could get the exact text of that error it might help; but probably the best thing is if I give you the standard response asking you to try the new kernels being developed - if you can give it a go it would be good to know if they fix it or if they give any different/better diagnostics Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications-Accessories-Terminal).

It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Neat.

Hi Alan, Have you tried doing a copy from a text virtual console (switch to it from ctrl-alt-f1 - you can switch back using ctrl-alt-f7 or f8) It's possible you might get a spew of error messages as it hangs on the console.
