[BCM4311] Segmentation fault when building bcmwl-kernel-source

[Ken Sharp]

While attempting to build bcmwl-kernel-source with DKMS (all automatic) a segmentation fault occurs and the system claims there is a bug in the kernel.

Copy/paste not possible and logs aren't saved so will update soon (testing upstream kernels).

Please look in /var/lib/dkms/... for build.log or similar. That will be the most useful log file.

[Ken Sharp (kennybobs)]

The only log files I could find in /var/lib/dkms/* are make.log files, and they all say the same thing which is not a lot. I've zipped them together to preserve the directory structure, just in case.

Tried three different kernels:

3.2.0-56-generic-pae
Segmentation fault during build.

3.2.51-030251-generic-pae (mainline)
Just stops. Nothing happens.

3.12.0-999-generic (today's daily)
Refuses to build.

[Ken Sharp (kennybobs)]

This screenshot is the only evidence I have of the fault.

[Ken Sharp (kennybobs)]

I cannot remember what the tag is for "cannot test upstream kernel" and I cannot find it down the right-hand side.

I forgot to scroll the screen up but it does say BUG in reference to the kernel rather than an oops.

[penalvch (penalvch)]

Ken Sharp, if you completely uninstall zram, and restart, is this still reproducible?

[Ken Sharp (kennybobs)]

I have since moved this machine to the Raring HWE (linux-generic-lts-raring) and the package builds with or without zram (which I have removed altogether).

I guess the issue is with the 3.2 kernel. I'll reopen if I get round to testing further with that kernel, but I have a feeling nobody is particularly interested in that scenario so will leave to expire for now.
