Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 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.

Same problem BUG: soft lockup - CPU#0 stuck for 22s!
with linux-image-3.13.0-37-generic on Pentium M processor
kernel 3.14 seems to solve the problem

[Sylvain Miossec (sylvain-miossec)]

Actually problem seems to come from linux-image-extra
I had not the problem with linux-image-3.13.0-36-generic
But since I was missing some drivers I added linux-image-extra-3.13.0-36-generic
Then I had the problems again
I remove kernel-fixed-upstream then. Where can I find linux-image-extra for upstream ?

[Sylvain Miossec (sylvain-miossec)]

I have found actually all drivers are included in mainline kernels. Then I tested mainline kernels to find out last kernel without bug.
Last kernel from mainline without bug is 3.11.10
Kernels I have tested that have bug :
3.12.0
3.12.30
3.13.11
3.14.21

So problem comes from the very beginning of 3.12 kernel development.
