Howdy list,

Just thought I'd post this description of the lockups
I've been experiencing and ask if anyone else is experiencing
the same thing?

If I attach my usb 2.5" 32Gb USB->ATAPI hard disk to my
IBM Thinkpad A30p running 5.2-BETA and do a dump of my
16G (used) /usr slice to the external drive then my machine
will lock up after transfering about 1 or 2 gigs of compressed
data to the external drive.

Also, I experience a similar lock up if I let the machine sit
for a few hours doing nothing.

This didn't happen under FreeBSD 5.1-RELEASE.

I'll try to do some testing with a serial console later today
and see if I can get a backtrace with the software watchdog
when the system locks. All of my previous lockups have occurred
while I was looking at KDE, so I don't know if the machine is
hard locking or panicing.

Just an FYI at this point...
