Subject: random panics in RELENG_6
To: freebsd-current@freebsd.org
Hi,
I'm having kernel panics often with RELENG_6 running on an old AMD K6-2 with
128 mb ram. Below is the stack trace from core file. I'm new to FreeBSD -
just trying it on my router for a few months. Can anyone help me to find out
what's happening?
Hardware used on this pc is ural usb wireless card, rl and dc network cards,
snd_cmi integrated soundcard.
It crashes one time in 1-2 days under normal load (web proxy,ipsec+racoon for
wifi, pppoe gateway to internet). But when I was building the kernel, it
crashed VERY often - ~10-15 times in a few hours until compilation was
done :)
