System was unusable. Between messages of #GP there were messages from nfs:
------------------------------------------------------------------
Jan 8 20:23:07 afbook kernel: [ 8810.002727] nfs: server 192.168.1.10 not responding, timed out
------------------------------------------------------------------

To reproduce I was watching videos using ethernet connection over nfs. Than I enabled wifi, connected to network, mounted nfs share and started smplayer to watch video, switched to console and watched for logs.

My WiFi controller is "Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)" and since lucid I'm using 'wl' driver from 'bcmwl' package.
