Steve, you can test the Broadcom proprietary wl. Open jocky-gtk and
install the Broadcom STA driver (like the ubuntu 10.10). Reboot : it
deactivates the brcm80211 driver.

Title:
broadcom 80211
I assume 11.04 also brought in a new kernel and new brcm80211/brcmsmac driver.
Is there any way on ubuntu to switch to the old firmware package (from 10.10)?
It would be good to know if it was the firmware or the updated driver that is
the root of the problem.

Which kernel package are you seeing this on? Are you still on 2.6.38-8?
Several bug fixes that resolved other kernel panics went into the driver
a few weeks ago. Perhaps those have not been picked up for the kernel
package you're using.

Some of the driver fixes deal with crashes that happen in less common
usage, such as roaming in an ESS (which you would only experience if
you have two or more APs in the same network).
For testing out newer driver versions with your current kernel, you
could try the compat-wireless package:
Thanks, it work with the 2.6.38 kernel. I use the linux-next compat-
wireless.
I think it is up to date. No differences between

After testing all the day, the patch works great. No kermel panic at this time
! The network debit is stable.
But same question : when will the 40MHz channels work ?

We're currently focused on stability and code cleanup to get the driver
out of staging. We have 40MHz channels, other features, and support for
new chips planned but no ETA at the moment.

The two patch work !
For those who want test it, I did this commands :
- git clone
git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
- wget
If I use git apply with the second patch, It doesn't do anything with this
command : git apply --binary patch2 .
With this command git apply --binary -p2 brcm/patch2 , I have this error :
fatal: git diff header lacks filename information when removing 2 leading
pathname components (line 3) .
If you have a copy of the linux-firmware repo, apply these two patches:

http://marc.info/?l=linux-wirelessm=130201555726958w=2
The new firmware will be brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw.
