It's RHEL6 kernel with brcmsmac backported from 3.5, but as I wrote
before the same crash happen on vanilla 3.5 and latest wireless-testing.

On RHEL memory dump works so I could grab dmesg after a crash. I put
photo from vanilla 3.5 here:

It's not NULL, RAX and RBX are 6b6b6b6b6b6b6b6b, so this is memory
usage after free kind of issue.

BTW: Arend, I'm testing brcmsmac currently and I hit various other
problems, in what form You (i.e. brcsmac developers) prefer to get
bug reports, mailing list, kernel bugzilla, something else ?
