I've spent the past four days or so updating machines here to 4.8/9-stable
via
cvsup, and have done a complete make buildworld/kernel on each machine (some
SMP, some single processor). It seems something is broken with the latest fxp
driver, on each machine (different mobos and hardware configs) heavy network
traffic with fxp NICs causes timeouts and random kernel panics.
First machine to experience the problem was a single proc PIII-650 with 512M and
Adaptec 2940UW, one fxp, doing a backup via scp, after 10 megs or so starting
giving fxp0 timeout errors and dropping the connection (host was not pingable
and dropped all arp entries). The only way to restart the scp was to ifconfig
fxp0 back up with the same IP and netmask.
Second machine is a dual proc PIII-650 with 512M, MegaRAID, one fxp - after a
minute or so of scp'ing the machine completely locked, had to be hard reset.
Second attempt caused a panic that seized entire machine with instant reboot.
Few more machines, same problems, all with varying SCSI subsystems and with one
fxp NIC. After replacing each machine's fxp with crappy tulip and/or $12
kmart
linksys NIC, I've had no problems at all.
