Hello.
My laptop just had a panic: I was not there at the time, so I just found out it
had rebooted.
kgdb says:

I guess the problem is in
/usr/src/sys/contrib/dev/ath/ath_hal/ar9300/ar9300_ani.c:1180:
1175 */
1176 if (!DO_ANI(ah)) {
1177 return;
1178 }
1179
1180 ofdm_phy_err_rate =
1181 ani_state->ofdm_phy_err_count * 1000 / ani_state->listen_time;
1182 cck_phy_err_rate =
1183 ani_state->cck_phy_err_count * 1000 / ani_state->listen_time;
Probably ani_state->listen_time is zero, but kgdb won't let me check.
This is 10.1/amd64 with
ath0@pci0:3:0:0: class=0x028000 card=0xe052105b chip=0x0034168c rev=0x01
hdr=0x00
vendor = 'Atheros Communications Inc.'
device = 'AR9462 Wireless Network Adapter'
class = network
Hope this is the needed info to track this down; otherwise, I'm willing to
provide.
This crash is quite rare, since my laptop usually works fine.
