Hello All,

During a 'cat /proc/bus/pci/00/00.0' This being a binary file
I decided to ^C & got my garbled prompt back , I then typed
'reset' and total lockup occured . no pings, no ....
I am not in the presence of console so I can't get to any on
console messages that may have occured .
I was ssh'd into the system at the time , if this makes any diff.

I had a tech on-site so had him reset it, after having him attempt
the obligitory ^-ALT-DEL which didn't produce results.
Below is the System info -after- the reset.

Hth, JimL
