After installing Mageia 1; upgrading the all of the installed packages including gcc and the kernel (2.6.38.7-desktop-1.mga -> 2.6.38.8-desktop-10.mga), and then; installing the Broadcom driver (dkms-broadcom-wl-5.100.82.112-2.mga) the kernel panics during boot...

kernel BUG at include/net/cfg80211.h:1780

I might have forgotten to reboot after upgrading all of the installed packages including gcc and the kernel and before installing/compiling the Broadcom driver. I can't remember - I was multitasking at the time!

The system will still boot the old kernel (2.6.38.7-desktop-1.mga) without complaint.

How can I fix this?

I've tried commenting-out the line in /etc/udev/rules.d/70-persistent-net that configures the Broadcom BCM4311 NIC...

Code: Select all

#PCI device 0x14e4:0x4311 (b43-pci-bridge)
# SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:92:26:b0", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

...but that doesn't seem to fix the problem.

I've tried using the LIVE-CD to mount the filesystem and remove the dkms-broadcom-wl-5.100.82.112-2.mga.nonfree RPM...

Code: Select all

# mount /dev/sda5 /mnt
# mount /dev/sda6 /mnt/var
# chroot /mnt
# rpm -qa | grep broadcom | xargs rpm --erase

...but that doesn't seem to fix the problem either.

In fact, the dkms module still exists...

Code: Select all

# cd /lib/modules
# find . -name 'broadcom*'
./2.6.38.8-desktop586-10.mga/kernel/drivers/net/phy/broadcom.ko.gz
./2.6.38.8-desktop586-10.mga/dkms/3rdparty/broadcom-wl
./2.6.38.7-desktop586-1.mga/kernel/drivers/net/phy/broadcom.ko.gz

Ideas? Suggestions?

I was able to boot the system using the previous kernel version (2.6.38.7-desktop586-1) and delete the kernel module (/lib/modules/2.6.38.8-desktop586-10.mga/dkms/3rdparty/broadcom-wl). This allowed me to successfully boot the system using the latest kernel (2.6.38.8-desktop586-10).

On a second, identical system that I had installed dkms-broadcom-wl on...

[root@localhost modules]# rpm -qa | grep broadcom

[root@localhost modules]#

I'd file a bug, but it's not reproducable - I've successfully removed+reinstalled the dkms-broadcom-wl RPM on the first system twice now!

FTR: The Broadcom 4311 WNIC works with the b43-openfwwf RPM.

Marking thread 'SOLVED'.
