CONFIG_INTEL_IDLE causing crashes?

From: J. Bruce Fields
Date: Fri Oct 05 2012 - 18:24:00 EST

I find that I can reliably crash 3.6 by booting to a kernel with
CONFIG_INTEL_IDLE set and running

dd if=/dev/zero of=BIG

If I turn off CONFIG_INTEL_IDLE there's no crash. (dd just hits ENOSPC
eventually.)

This isn't new--I originally saw it on 2.6.35.6. (An upgrade to F14
failed, and by trial and error I found CONFIG_INTEL_IDLE seemed to make
the difference.)

I only see it on this one machine, which has an i7-870 and discrete ATI
graphics. Another machine with an i3-530 and integrated graphics, but
otherwise similar hardware (they were built from the same barebones), is
not crashing.

The first oops messages from one such crash follows. (For what it's
worth, my memory is that they aren't always in ext4--but I don't have
any others in front of me.)

Any ideas? Let me know of anything else that might be useful.

--b.
