Description Satish Balay 2013-01-14 16:19:12 UTC
Description of problem:
machine crashed when attempting to suspend.

this is F18 with rawhide-nodebug kernel with the following
in /etc/modprobe.d/i915.conf [to conteract overheating machine]

options i915 modeset=1
options i915 i915_enable_rc6=7
options i915 i915_enable_fbc=1
options i915 lvds_downclock=1

I guess one of these options is a cause [so will remove and recheck overheating issue]

Comment 1 Satish Balay 2013-01-15 17:33:34 UTC

overheating issue appears to be fixed with this rawhide nodebug kernel [without requiring options to i915 module].

And the machine hasn't crashed in the past 24 hours.
