bwn panic

[Ruslan Mahmatkhanov]

Hello!

I'm using

siba_bwn0 at pci0:16:0:0:	class=0x028000 card=0x1364103c chip=0x431114e4 
rev=0x01 hdr=0x00
     vendor     = 'Broadcom Corporation'
     device     = 'Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI 
Card (BCM4311)'
     class      = network

with bwn driver on recent stable. I'm using it with wpa_supplicant for 
WPA2 encryption. It works well most of the time, but right now (it was 
first time) i get my laptop rebooted with following in messages:

Jun 25 17:40:05 smeshariki2 kernel: --> or switch off the system now.
Jun 25 17:40:05 smeshariki2 kernel: Rebooting...

I know nothing but it looks like some locking issue.
Can please anybody shed some light what's wrong? Thanks.
