Hi,
Toshiba R600, snv_127
From time to time nwam can't configure iwh0 interface. If i restart
nwam then usually it helps and it works fine. But sometimes it doesn't
help and I have to reboot OS to recover.
When it helps I can see in logs:
Dec 1 11:50:12 r600 iwh: [ID 450215 kern.warning] WARNING:

Dec 1 11:50:12 r600 iwh: [ID 808906 kern.warning] WARNING: iwh_init():

Dec 1 11:51:08 r600 mac: [ID 744254 kern.info] NOTICE: iwh0 link up
Then I suspended the system and resumed it again:

So it took almost 10 minutes to recover and finally configure iwh0
again. But sometimes I have to reboot the laptop so it recovers (or
maybe I wasn't patient enough?).
I'm not 100% sure but I believe that it also happens sometimes even
without going thru suspend/resume cycle. At least it did on older builds.
