Hello,

It crashed again with the patches, this time I got a picture:
http://home.comcast.net/~jpiszcz/20110815/26030-kernel-crash-when-cifs-mount.jpg

The machine is up no issues until you try and mount a CIFS share, then
the problem occurs, every time (and with the patches as well).

3.0.1+80975d21aae2136ccae1ce914a1602dc1d8b0795
      +f9e8c45002cacad536b338dfa9e910e341a49c31

Same result.

Justin.
