Allison Randal, thank you for reporting this bug and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so could you please attach the results following https://wiki.ubuntu.com/Kernel/DebuggingSchedulingWhileAtomic ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> 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 . 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. Thanks in advance. ** Summary changed: - [STAGING] Eee PC 1015PEM unstable on 2.6.38-6-generic + [STAGING] Scheduling while atomic: swapper/0/0x00000100; RIP: 0010:[<ffffffff813354ca>] [<ffffffff813354ca>] intel_idle+0xca/0x120 ** Tags added: kernel-bug ** Description changed: I'm having trouble with random intermittent crashes on Natty (Classic Desktop), on an Asus Eee PC 1015PEM-PU17. I've attached a screenshot of the crash, apport didn't catch a crash report for it. It's a hard crash, have to reboot. No apparent connection to any user action (I can be typing in a terminal/text document, surfing web browser, whatever). There *might* be a connection to the Broadcom STA wireless driver, the crashes are apparently more frequent on a flaky conference network (but that's a purely subjective observation). + + WORKAROUND: intel_idle.max_cstate=0 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-6-generic 2.6.38-6.34 Regression: Yes Reproducible: No ProcVersionSignature: Ubuntu 2.6.38-6.34-generic 2.6.38-rc7 Uname: Linux 2.6.38-6-generic x86_64 NonfreeKernelModules: wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
