I'm having lockup problems with a Compaq Prolinea 5100. It's an
old Pentium-100 that's been working fine with 3.3. It's locked
up 6 times in the last month or so since 4.2 was installed.
The machine is currently using sources cvsupped 12/25/00 at
about 20:45 (-0600). I've tried to come up with kernel debug
information but since it's my first stab at this I'm sure it's
incomplete. I'd appreciate any pointers here.
Matt
