Hello!

I'm using

siba_b...@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 17:31:51 smeshariki2 wpa_supplicant[424]: CTRL-EVENT-SCAN-RESULTS

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.
