I've filed a bug on the broadcom-sta package, suggesting that it could provide a configuration file to blacklist brcm80211. However, I think we should continue to provide brcm80211 in the kernel image packages as there is some value in a free driver that doesn't have to be built by the user. We can apply upstream fixes for the locking bugs later.

Re: 3 system freezes after upgrading to 2.6.32-23: advice needed
I have blacklisted the brcm80211 module and worked all day without a problem. I googled to http://linuxwireless.org/en/users/Drivers/brcm80211, where it is stated that "43224/5 has a locking issue, stable with maxcpus=1, can crash otherwise after random period." which pretty much matches my case. Thanks for the advice, Ben.

You could try blacklisting the brcm80211 driver, so that the wl driver will be loaded instead. To do this, run: echo blacklist brcm80211 > /etc/modprobe.d/brcm80211.conf Then switch to the wl driver: rmmod brcm80211 && modprobe wl If this fixes the problem then we know that this is really a bug in brcm80211.

3 system freezes after upgrading to 2.6.32-23: advice needed
Hello list, This morning I have upgraded my notebook from kernel linux-image-2.6.32-5-686-bigmem from 2.6.32-21 to 2.6.32-23. During the day I have had 3 system freezes: blank screen, no keyboard lights, no remote ssh, no alt+sysrq. All the 3 freezes seem to have happened at moments of system inactivity. Notable was that the wifi light was turned off on all 3 freezes, despite the fact wifi was on previously. This notebook is a Dell Vostro and has a Broadcom Corporation BCM43224, and I am using the broadcom-sta driver from sid. In the logs there is a "brcm80211: module is from the staging directory, the quality is unknown, you have been warned." In the changelog I see there was activity in this driver, and I had to manually download its firmware (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597034#10), so this is my first suspect. Since there is no other clue in the logs, I turn to this list for advice on how to proceed on this issue. regards, Pedro -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
