Bug Description

After today's updates for Raring (including the 3.7.0-6 kernel, a boot shows a GPF; the system keeps on, but is unusable (not possible to complete logon to KDE, some commands never end, etc).

*NOTE* Still fails on 3.7.0-7.

Eventually I was able to recover the system by booting from a rescue image, and blacklisting:
wl
mac80211
cfg80211.

My system carries a Broadcom wireless chip:
03:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)

This is the error:

Hey Carlos,

It would be good if we can narrow down the last good kernel and first bad kernel. It sounds like you are seeing this on:
3.7.0-5 and 3.7.0-6.

3.7.0-5 was rebased to upstream v3.7-rc8, so it would be good to test the following kernels:

v3.7-rc5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/
v3.7-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc6-raring/
v3.7-rc7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc7-raring/

You don't have to test every kernel, just up until the kernel that first has this bug.

Thanks in advance!

All of rc5, 6, and 7 fail the same. Interestingly, previous kernels do not fail -- because there is no 'wl.ko' anymore for them. Today I did download and install a new Broadcom STA source package -- 6.20.155.1+bdcom-0ubuntu1. It seems it was built only for the 3.7.x kernels.

Undupping from bug 1089157 -- that bug is on kernel 3.7.0-5, and downgrading bcmwl to 5.100.82.112+bdcom-0ubuntu4 works.

On 3.7.0-6, bcmwl at versions 5.100.82.112+bdcom-0ubuntu4, 6.20.155.1+bdcom-0ubuntu1, and 6.20.155.1+bdcom-0ubuntu2 cause a kernel crash.

The v3.8-rc2 kernel is now available. Can you test this latest kernel to see if the bug still exists?

One other question, in comment #5 you mention that previous kernels do not fail. Does that mean v3.7-rc4 does not exhibit the bug?

Note that this is related to the bcmwl package: the kernel works OK until the 'wl' module is loaded, when it immediately crashes. This test was run with the current bcmwl (6.20.155.1+bdcom-0ubuntu4; all of the 6.20.155.1 bcmwl packages cause the failure).

The associated bug is bug 1089114.

Additionally. Until 3.7.0-6 and the first bcmwl 6.20.155.1, all was fine. On 3.7.0-6 bcmwl 5.100.82.112+bdcom-0ubuntu4 caused a kernel crash (see bug 1089114). I have been running Raring through all kernels released without any problems until 3.7.0-6 *and* bcmwl 6.20.155.1.
