It's hard to tell for sure, of course (memory corruption can do pretty much anything), but I'm not seeing the 07200720.. pattern at least. And some of them do seem to be bisected to likely culprits and/or have patches that are claimed to have fixed them. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=16163 > Subject : [2.6.35-rc1 Regression] i915: Commit cfecde causes VGA to > stay off > Submitter : David John <david...@xenontk.org> > Date : 2010-06-02 12:52 (7 days old) > Message-ID : <4c065423.3000...@xenontk.org> > References : http://marc.info/?l=linux-kernel&m=127548313828613&w=2 That has a "reverting the commit fixes it", and a confirmation from Nick Bowler. Eric, Carl: should I just revert that commit? Or do you have a fix? > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=16145 > Subject : Unable to boot after "ACPI: Don't let acpi_pad needlessly > mark TSC unstable" > Submitter : Tom Gundersen <t...@jklm.no> > Date : 2010-06-07 13:11 (2 days old) > Handled-By : Venkatesh Pallipadi <ve...@google.com> Hmm. This does seem to be a properly bisected commit, but at the same time it looks from the bugzilla like it's just pure luck on that machine that the acpi_pad driver happened to mark TSC unstable - so while the commit bisected is the real one, it's not the "deeper reason" for the problem.

Most of the time sched_clock() is called with irqs disabled already. The few places that call it with irqs enabled need to be updated.

Both are related to that "slot" thing in sysfs PCI, but only one of them is marked as Jesse's.
