Default Bug#602444: firmware-brcm80211: Kernel Panic on "iwlist scan"

Package: firmware-brcm80211
Version: 0.27
Severity: critical
Tags: patch
Justification: breaks the whole system


Booting the "HP Mini 5103" with the firmware-brcm80211 package installed leads
to a 100% reproducible Kernel Panic. (Squeeze's 2.6.32 and experimental
2.6.36-trunk are affected).

>From the http://linuxwireless.org/en/users/Drivers/brcm80211 homepage, the fix
is to load the module with maxcpus=1.

So a simple patch would be to ship a /etc/modprobe.d/brcm80211.conf containing

options brcm80211 maxcpus=1

I tested that here and it works. So, of course having said driver run on one
CPU only is sub-optimal, but at least the Kernel Panic is avoided.

This should make it in Squeeze IMHO.

Cheers, OdyX
