system locked up

[Jeremy C. Reed]

A few times my laptop locked up today.

Locked up where I can't ping it. I was in X and couldn't do anything.

The last time it locked up, I unplugged the USB-based ral0 and plugged it
back in.

No logs in messages.

Running NetBSD/amd64 4.0_RC4

ral0 at uhub5 port 2
ral0: Cisco-Linksys Wireless-G USB Network Adapter, rev 2.00/0.04, addr 4
ral0: MAC/BBP RT2570 (rev 0x03), RF RT2526
ral0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ral0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps
24Mbps 36Mbps 48Mbps 54Mbps

The system has been stable. It has only been off once before today (got
accidently unplugged and battery died) since I initially installed it in
November when I purchased it. It is a Toshiba A215-S7422.

The three things that have changed for me:

- using re0 which I never used before

- using PF. I enabled with:

modload /usr/lkm/pf.o

pfctl -ef /etc/pf.conf

And my config is simply:

tx:reed$ egrep -v '^$|^#' /etc/pf.conf
nat on ral0 from !(ral0) -> (ral0:0

- And "sysctl -w net.inet.ip.forwarding=1"

(I did those three things to share network for an IP phone.)

I am no longer using re0 -- it is UP by default (as it always was) -- but
nothing plugged into it. And I don't have pf module loaded and forwarding
is 0 (default). Hopefully my system will be stable now.
