I've updated the BIOS to the latest version A05. The kernel panics on boot persist in the Ubuntu Trusty kernel. 3.13.0-66-generic still often fails to boot. Patched kernels I've built have never failed to boot. ** Tags removed: bios-outdated-a02 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482273 Title: Dell Ubuntu 3551: failure to boot without nolapic option To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482273/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1482273] Re: Dell Ubuntu 3551: failure to boot without nolapic option
I have tested the attached patch against ubuntu kernels 3.13.0-58,
3.13.0-63, 3.13.0-64, and 3.13.0-65 for over a month. Never once has
this laptop suffered a kernel panic with the applied patch to reinstate
the optimization to stepwise.c. It has never failed to boot. As I said
earlier, I found the origin of the regression through a git bisect.
I also have tested the latest upstream kernel, version
4.3.0-040300rc3-generic #201509271225. It has no issue booting. Looking
at:
https://github.com/torvalds/linux/blob/master/drivers/thermal/step_wise.c
I see that the commit which introduces this issue has not been applied
upstream. Probably because commit
178c2490b99f898efc06d1ad75cadc84f13021a6 (thermal: step_wise: Revert
optimization) is not needed due to
8c8dd64345ba2a8c41556095c7adacb1c8af7c1 ("acerhdf: Use bang-bang thermal
governor") fixing the issue for the fan control upstream. So the issue
I'm experiencing is not so much fixed upstream, as rather it never
existed upstream.
I do have an old Acer Aspire 1410 which uses the acerhdf fan control
module if you would like assistance in testing a backport of
8c8dd64345ba2a8c41556095c7adacb1c8af7c1 ("acerhdf: Use bang-bang thermal
governor") to 3.13.0.
Ubuntu kernel 3.13.0-65-generic is still unable to reliably boot without
a kernel panic.
Thanks

[Bug 1482273] Re: Dell Ubuntu 3551: failure to boot without nolapic option
Mark Standridge, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: bisect-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482273 Title: Dell Ubuntu 3551: failure to boot without nolapic option To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482273/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think I've found the bad commit that introduced this bug, dc487e5b0e9e401e9705dc4c62b9170711c68f77 thermal: step_wise: Revert optimization. I have extensively tested kernels 3.13.0-63 and 3.13.0-64 after this commit is reverted and they boot without issue and run without crashing. Reverting this will expose a bug in the acerhdf fan module preventing fan control on some old netbooks. diff --git a/drivers/thermal/step_wise.c b/drivers/thermal/step_wise.c index d89e781..769bfa3 100644 --- a/drivers/thermal/step_wise.c +++ b/drivers/thermal/step_wise.c @@ -140,9 +140,6 @@ static void thermal_zone_trip_update(struct thermal_zone_device *tz, int trip) old_target = instance->target; instance->target = get_target_state(instance, trend, throttle); - if (old_target == instance->target) - continue; - /* Activate a passive thermal instance */ if (old_target == THERMAL_NO_TARGET && instance->target != THERMAL_NO_TARGET) I have attached the git bisect log.

Mark Standridge, as per www.dell.com/support/home/us/en/19/product- support/product/inspiron-15-3551-laptop/drivers an update to your computer's buggy and outdated BIOS is available (A02). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed.

[Bug 1482273] Re: Dell Ubuntu 3551: failure to boot without nolapic option
Nevermind, this bug is still present in 3.13.0-63-generic. I was wrong about the bios setting in post #5. The only reliable way to boot a current kernel with working smp is to first boot linux- image-3.13.0-57-generic, then reboot into the latest kernel. Kernels linux-image-3.13.0-62-generic and linux-image-3.13.0-63-generic do run stable once booted, the others I mentioned earlier are unstable if booted. On a related note, I see Dell has stopped offering the Ubuntu Edition of this laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482273 Title: Dell Ubuntu 3551: failure to boot without nolapic option To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482273/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1482273] Re: Dell Ubuntu 3551: failure to boot without nolapic option
I have discovered one cause of the kernel panic during boot that affects this laptop with linux-image-3.13.0-61-generic and linux- image-3.13.0-58-generic. Within the UEFI BIOS settings is an option called "Battery Charge Configuration." Both kernels boot without issue when "Standard" option is selected but fail to boot when "Primarily AC Use" is selected. This is also the case with linux- image-3.13.0-62-generic from the canonical-kernel-team ppa. Perhaps this information could be of some use to others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482273 Title: Dell Ubuntu 3551: failure to boot without nolapic option To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482273/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm that this bug is fixed in linux- image-3.13.11-031311ckt24-generic. The kernel boots and all cores function. The oem-audio-hda-daily modules failed to build due to a version check when installing this kernel. I purged oem-audio-hda-daily and dkms then attempted to boot the affected kernels. They still failed to boot. The problem is thus fixed in the upstream stable kernel.

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 stable kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
