I think this is the same issue as http://bugzilla.kernel.org/show_bug.cgi?id=13751 . The root cause of 13751 seems to be a BIOS defect in SMI handling that corrupts registers or memory when the SMI handler runs somewhere other than CPU 0. One way to workaround it is to boot with "nosmp". Another is to do something like comment #33, which prevents the software-initiated SMI.
But I think the best way is to use the kernel patch I attached to 13751, which works around the BIOS defect directly by forcing the software SMI initiation to run on CPU 0. This should solve the problem without requiring any user-space workarounds. ** Bug watch added: Linux Kernel Bug Tracker #13751 http://bugzilla.kernel.org/show_bug.cgi?id=13751 -- Hardy/Gutsy crashes when the lid is closed on a HP 6710b, HP 6510b and HP 2510p https://bugs.launchpad.net/bugs/157691 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
