System hangs after running 2.6.17rc6 with broadcom 4309 and device scape stack

[Alex Davis <alex14641@yahoo.com>]

After running 2.6.17rc6 with device scape stack 
(git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-dev.git)
for a few hours, my system hangs. Here is the last thing I see in my logs:

This has happened daily during the two days I've been running this version.

My log also has lots of these messages:

The system hangs so hard not even alt-sysrq can wake it up.

This problem did not occur in the 2.6.17r4 or rc5 versions of the dscape stack.

System is a Dell Latitude D600 laptop.
