Comment (by [EMAIL PROTECTED]):
I had a similar panic with madwifi 0.9.4 panic and 2.6.24. I believe the
system was in the middle of rebooting and wpa_supplicant was bringing the
interface down.
Here is the panic from a Au1550 (MIPSLE) system:
{{{
ath_rate_minstrel: no rates for 00:02:6f:4a:c2:22?
ath_rate_minstrel: bad rc1 (0/0) for 00:02:6f:4a:c2:22?
