[Bug 666371] [NEW] Broadcom B43 driver does not survive a suspent/resume

[Jeff Lane]

Public bug reported:

This is a regression from Lucid, I believe. Also, opening this per a
discussion with JFo at UDS.

So, I have a Lenovo S10 netbook with a Broadcom BCM4312 wi-fi card.  To
use this card, I have to use the Broadcom B43 driver (b43.ko) and it
does not do well after a suspend/resume cycle.

Steps to reproduce:

Maverick on a system w/ B43 based wi-fi
boot, connect to AP
Suspend system
Resume system
wireless no longer connects to APs found on scan, lots of error messages in /var/log/syslog

I've tried just bouncing the B43 driver as a workaround, but that
doesn't work either.  I have to fully reboot after each suspend to get
wireless working again.

I'll try the STA driver shortly to see if that fares any better.

The error messages seen in syslog are like the following:

This happens after each suspend/resume cycle and requires a reboot to fix, as mentioned earlier.
