i have a new system, dual pentium 550's, 512meg ram, dual adaptec 29160,
realtek ethernet. (dmesg.boot enclosed)
it has been having intermittent reboots, with no syslog output.
i thought maybe we were having heat issues, or power issues, but maybe it
is a kernel bug.
i enabled dumpdev and now i have dumps.
(arg, and it just crashed while i was snarfing the attached info)
both crashes occur in the same place in the kernel.
i think maybe that indicates a potential kernel/driver bug.
please find attached:
dmesg.boot
gdb -k info - crash 0
gdb -k info - crash 1
last second info:
nuffy# ifconfig rl0
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 209.167.108.145 netmask 0xffffff80 broadcast 209.167.108.255
inet 209.167.108.146 netmask 0xffffffff broadcast 209.167.108.146
ether 00:00:21:ef:1d:a4
media: autoselect (none) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
is it possible that the bug is being triggered because the driver has not
selected a media type?
i did notice that the ethernet performance sucked, but i wasn't sure if that
was because the machine i was ftp'ing to sucked, or because this interface
was not specifically set to a media.
i elected not to set the media, because the machine is remote from me, and
didn't want to have it lose the connection.
i will physically visit the machine tomorrow.
