Description Krzysztof Grygiencz 2011-04-03 12:47:02 UTC 
Hi,

I've noticed that after kernel upgrade from 2.6.37.5 to 2.6.38.x, mouse cursor freezes for a fraction of a second. It's nearly 100% reproducible and always happens on WM (openbox) start. Also when I watch tv or movies in (s)mplayer, screen freezes for a fraction of a second.

I've tried to bisect this and found that this commit is responsible http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=commit;h=6254b32b5791e47ba1c679d023f26985fa34755a

I know that this bug has nothing to do with Linus fix to ecryptfs, but it's the changes between those two snapshots are causing screen/mouse cursor lags.

good - http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=snapshot;h=17db143fc091238c43ab9f373974ca2224a4c3f8;sf=tgz

bad - http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=snapshot;h=6254b32b5791e47ba1c679d023f26985fa34755a;sf=tgz

You can close this bug. I don't have this lockups anymore. Maybe it was something wrong with my hardware.
