Public bug reported:

Binary package hint: linux-image

From:

http://ubuntuforums.org/showthread.php?t=725786

When my "AIRONET Wireless Communications Cisco Aironet Wireless 802.11b"
card seems to be having trouble with a wifi signal, the entire system
freezes, often with the caps lock blinking. I've attached syslog entries
from the time of a crash.
