Now the report...
I'm reporting a kernel panic with a 6.0-STABLE machine using RELENG_6
source from 2006-11-09.
It was triggered when I ran the command "ifconfig ath0 pureg" as an
attempt to switch the D-Link G520 running in hostAP mode, into "g
only" mode. I did this because I've been experiencing slow rates with
Airport Express clients (PowerBook) where no matter what the settings
on the AP are, it refuses to go above 1 Mbit/s.
Here's the pertinent debug info:
from /etc/rc.conf
# ath0 to be bridged with fxp0. See /etc/sysctl.conf
ifconfig_ath0="inet up ssid FOO mode 11g mediaopt hostap -wme wepmode
on wepkey 1:hexkeyhere authmode shared deftxkey 1 pureg"
Notice the "pureg" directive in there.. I added that after doing the
interactive test mentioned above, which crashed the system. It seems to
be ok if it's enabled at boot time.
Also, I'm using bridge(4), so here's the relevant sysctl(8) oid:
net.link.ether.bridge.config: fxp0,ath0
