Hi,
I just updated my laptop (MacBook Air 2012) from 3.11-rc3+ to 3.11-rc4+
and since then brcsmac crashes short after enabling it. Unfortunately, I
did also change some config flags in the area of cpufreq (enabling
p-state driver) so the configuration is not exactly the same. Before I
try to figure out what I have changed, I am posting the picture of the
crash. Maybe it is something obvious.
v3.11-rc4-197-gd92581f

Thanks, Daniel
I was looking at this issue two weeks ago and just got back from my
vacation. Can you apply the patch and send me a kernel log?
Sharing pictures, huh. What about this one :-p

Arend

Sure, the patch does the trick, the panic is gone.

Unfortunately, it results in a lot of error print and phy tx errors that
has been reported by others. I think the two are related, but I have not
root caused it yet. Your laptop may be usable now, but wireless
performance is probably bad.
Too bad I can not reproduce the issue over here. Are you willing to test
some patches when I got a better grasp on the issue?

Arend
