@Tom Ellis: can you try reverting the commit
cdaa050bd1c658c5b808a35a1fc061038ad19bc5 ("x86: Flush TLB if PGD entry
is changed in i386 PAE mode") from the Ubuntu-2.6.32-32.62 kernel, build
a -pae flavour and ask for testing?I think it's likely this commit play a role in this bug, since it's inside the last bad/good window from your last bisect log (f1809971f60bf42ff9b47eac395e8729ed6bd525..1198ae36cd30092718563b42e2f1d847516a5e45), and this commit affects the PAE path, adding a flush_tlb_mm call that also appears on the soft lockup trace. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/805209 Title: System locks up after upgrading to linux-image-2.6.32-32-generic-pae To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/805209/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
