Package: xserver-xorg-video-intel
Version: 2:2.9.1-2
Severity: important

--- Please enter the report below this line. ---

I have recently installed a KVM switch. When switching to anothercomputer and back again, the xserver sometimes freezes. In thissituation, switching to a console using [ctrl]+[alt]+[f1] doesn't workany more. The system neither reacts on keyboard input nor on a usb mouseany more. However, the mouse cursor does move when using the notebooktouchpad (but mouse buttons don't work). The sysreq functionality isstill working. I've attached a log file of the problem. It contains asegfault and the message "[mi] EQ overflowing. The server is probablystuck in an infinite loop.".
