Any thoughts on this error?
I've run 3 memtest passes and put the box under severe CPU / disk / I/O load etc and there are no issues, but it appears when USB devices get used, the kernel panics. Next test will probably be to remove all USB devices and just use PS/2 and see if the problem goes away but I was curious if anyone could comment on the that dump: http://home.comcast.net/~jpiszcz/20110705/IMG_2875.JPG
As to what might be causing this otherwise? Thanks!
Memtest86 v4.20(latest): 3 passes, no problems: http://home.comcast.net/~jpiszcz/20110706/IMG_2879.JPG
