Hi,
After a suspend/resume cycle I see intermittent high latency in
poll_schedule_timeout (latencytop). This leads to the mouse cursor
freezing for several seconds sometimes when switching to/from a window
of a wine process. The problem never occurs before suspend, but always
occurs after. Any ideas what could cause such behaviour? Kernel is
vanilla 2.6.38 x86_64 running on a recent HP laptop with Intel chipset.

Was this solved somehow? Can you try to find "smaller" testcase --
anything less complex than wine? What about hibernation?

Yes, I made an educated guess and applied
84ac7c
x86, mtrr, pat: Fix one cpu getting out of sync during resume
With that the problem is gone.
