Greetings,
We're running 3.3-REL on dual processor PII-450's, with a N440BX
motherboard, using the onboard EtherExpress Pro (fxp) NIC and 512MB RAM.
These machines are running custom software that excercises the disk, CPU
and network quite heavily. The SMP machines seem to have both "fxp0:
device timeout" problems, and spontaneous reboots. We were uable to get
a working savecore until now, and have traced the reboots back to the
fxp driver as well. Here are the debug outputs, and any custom changes
to our kernel config.
Could this be a problem with SMP + fxp combination? Any other thoughts
or ideas?
We've serached, and read, and searched all the FAQ's for both of these
problems, and have pretty well come up empty. Suggestions for the next
course of action?
Thanks in advance for anyones help.
Regards,
Stevan Arychuk
