System freezes with 2.6.33

Hi,

After upgrading my system to 2.6.33
(http://www.archlinux.org/packages/core/i686/kernel26/) I am
experiencing complete system lockups.

I confirmed that this happens when the b43 drives is on ahd I try to
connect to the network. When I remove the module, the system works fine
for hours. When it is on, I have a few minutes, till a complete freeze.

There is nothing in the kernel logs, or dmesg, or anywhere I could
find. I tried reinstalling the firmware, but it didn't change anything.

The hardware is HP-2133 (mini note).
