Hi,

Does your Xorg log contains "Failed to submit batch buffer, expect rendering
corruption: Device busy" messages after a suspend/resume cycle? I was also
experiencing this sluggishness a while back on 10.0-STABLE, and found this
little patch for xf86-video-intel:

It's ugly, but it works for me.

Cheers,
Toma
