Anyone with the same problems ?

Anyway; Great work on the driver so far :D

I've similar issues and believe it might be due to the amount of
kernel printfs that are happening. Can you sysctl debug.wpi=0 and
see if the problem still exists?
By chance are you using ZFS? I caught a memory modified after free
panic in zfs the other day pid was from syslogd. I'm trying to work
out if it's related.

When setting debug.wpi to 0 it seems like the problem is gone. I'm
not using ZFS by the way. I did have a problem connecting to the AP
at my university though; the driver wouldn't assosicate whatever I
tried. I didn't have a chance to do some extensive testing though. It
might be because of the WEP+wpa_supplicant + ca certificate method
that is required to authenticate. Anyway I'll let it know if there is
an actual problem with the driver itself

Rule of thumb in debugging wireless issues (and most others for that
matter): simplify your config if at all possible. In this case try
checking things out w/o wpa_supplicant (i.e. no crypto).

When debugging, start at the top and work your way down to rule out
problems at each layer. In this case collect a wpa_supplicant debug
log first, then check for issues at the net80211 layer (wlandebug,
wlanstats, etc.), then finally check at the driver level.

For at home wpi is working fine, and I indeed used the method you
described above. Unfortunately I don't have the luxury of that extended
testing methods at my university since I can't turn off encryption and
the weird authentication methods there ;)

Hello,

Here it works for a while with debug enabled even with wpa_supplicant,
but after a few minutes the console output stops working, but the
keyboard is still handled ok. The Caps lock led blinks when the key is
pressed and ctrl-alt-del can reboot the box.

When debug is disabled and wpa_supplicant is on, it crashes after a few
seconds and gets me into the debugger.
I'll try later with unsecured networks and see if that happens again.
