From the bug report, the bug will be reproduced several times a day
under heavy activities. Compiz was launched on my M10 which I believe
would cause heavy activities, but I didn't catch the freeze. The patch
created by Jurgen is a possible fix for the potential bug and at least two
users reported the patch fixed their bugs alike. The i915 replacement module
built from the patch is in Opensolaris bug 12528.

Hello,
recently I've discovered that b134 sometimes freezes for few seconds -- usually after some
GUI activity is performed or during it. First I've though this is similar to this thread:
http://www.opensolaris.org/jive/thread.jspa?threadID=126157&tstart=0 but I'm not sure
now since it does not happen regularly but just from time to time. I've also observed that
after the "freeze" the dmesg contains message like:

If I grep for it /var/adm/messages I get this for recent days:

The symptoms of "freeze" is that GUI freeze completely for a few seconds. Mouse
is not moving (even if I try). Nothing change, etc. For example if I start gnome-terminal
and freeze happen during its start I see terminal window but its backgroud is gray and
not yet painted into black as it should be. And when GUI is unfreezed, then terminal
normally repaints and continues in its initialization. Looks like freeze happen just
during some GUI operation...
My question now is if this is already a well known issue or if I shall report
it somewhere.
Thanks,
Karel
