Comment 1 Peter Hutterer 2012-06-26 03:30:53 UTC
any chance you remember how you triggered this?

Comment 2 Owen Taylor 2012-06-26 03:41:47 UTC
I'm pretty sure there was no clear reproduction when it happened, I was just doing "normal stuff" and the server fell over.

Comment 3 Peter Hutterer 2012-06-26 04:02:36 UTC
sorry, really can't tell. smells a lot like list corruption or property corruption, likely after the vt switch, but I couldnt' reproduce this here yet. If it 's property corruption, could be evdev or synaptics too.

Closing this for now, if you notice this again please reopen.
