Within the past 4 days that I've noticed (didn't update ports for two 
weeks) X keeps freezing and/or crashing, sometimes when switching to a 
VT, sometimes when firefox crashes. Trying to restart it, results in the 
console locking up, X taking up 100% WCPU, with the following in Xorg.0.log

(WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled
(WW) intel(0): PRB0_HEAD (0x5301c9dc) and PRB0_TAIL (0x0001ca08) 
indicate ring buffer not flushed
(WW) intel(0): Existing errors found in hardware state.

Which requires a reboot to clear/get X to start up again.

Also, my mouse scroll wheel stopped working (ps/2) with the update, from 
the mailing list, saw that removing this file, 
would get it working again, which it did.  With the first crash, I 
recompiled with that file and X is still crashing and locking up the 
(EE) xf86OpenSerial: Cannot open device /dev/psm0
(EE) PS/2 Mouse: cannot open input device
(EE) PreInit failed for input device "PS/2 Mouse"

Can anyone shed some light into this?
