Bug Description

After install kubuntu 12.10 i havent second thread on CPU. On 12.04 work good. CPU: AMD C-50, laptop: Acer Aspire One 722. The following did not help:
+ BIOS upgrade.
+ Kernel parameter:
noapic acpi=off

WORKAROUND: Use both kernel parameters:
pci=nomsi
pnpbios=off

Marcin Janowski, thank you for reporting this and helping make Ubuntu better. Could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelBoot ?

As well, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

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 text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Please let us know your results. Thank you for your understanding.

Were you using your WORKAROUND during this test? If so, please undo it and repeat the test.

Don't worry about this for mainline testing as we are only concerned with if both your threads are recognized.

It looks like the IPI to wakeup the CPU at boot is not getting through. Just to sanity check things, can you also test with just the kernel parameter: "noapic" and see what happens. The output from /proc/interrupts on the working 3.6 and not working 3.5 kernel would be useful too.

Marcin Janowski, using an upstream kernel is unsupported. For more on this, please see https://wiki.ubuntu.com/Kernel/MainlineBuilds#Kernel.2BAC8-FAQ.2BAC8-DebuggingMainlineBuildsSupport.Does_the_kernel_team_support_the_mainline_kernel_builds.3F .

Marcin Janowski, as per http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-quantal.git;a=shortlog;h=HEAD;pg=2 the last known bad Ubuntu kernel 3.5.0-17.28 is based on mainline 3.5.5. The last known good mainline kernel is v3.6.2-quantal.

So, the next step is to perform a reverse mainline kernel bisect from 3.5.5 to v3.6.2-quantal, in order to identify the last bad upstream kernel version, followed consecutively by the first good one. As per http://kernel.ubuntu.com/~kernel-ppa/mainline/ we have:
v3.5.5-quantal/
v3.5.6-quantal-ok/
v3.5.6-quantal/
v3.5.7-quantal/
v3.6-quantal/
v3.6-rc1-quantal/

Marcin Janowski, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.11). If you update to this, does it change anything? If not, could you please test Raring via http://cdimage.ubuntu.com/daily-live/current/ ?
