Hi,
I'm using a Broadcom BCM4312 with i386 FreeBSD-8.0 updated May 08
2009. Ports up to date. Using net/bwi-firmware-kmod. Loading
first bwi_v3_ucode and then if_bwi.
When starting the supplicant, it associates fine and it works for a
period of time. From time to time I start to lose signal, I'm my log I
can see the following message :
May 11 08:42:51 gusiport kernel: bwi0: firmware rev 0x0127,
patch level 0x000e
May 11 08:42:51 gusiport kernel: bwi0: bwi_intr: intr PHY TX
error
Many of those messages per second. This is the first problem with
if_bwi. It forces me to restart by hand the wlan1 device associated to
bwi0. And here comes the freeze (the second problem I encountered). If I
try restarting like this :
/etc/rc.d/netif stop wlan1 && /etc/rc.d/netif start wlan1
it works (until the PHY TX error appears againg). If I try like :
/etc/rc.d/netif restart
or if I try :
/etc/rc.d/netif stop bwi0
the machine freezes. If i try to kldunload the module while in use
(if there's a wlan device created) the machine freezes too. It can be
unloaded only if there is not any wlan associated to the bwi device.
