You are on 3.9.0-rc2, so there is nothing for us to backport on these linux-next based releases except the delta between v3.9 and what is not yet on Linus' tree, in other worlds just the development delta for the 802.11 subsystem. We have yet to require any backport work between 3.9 and what we assume will be 3.10. My bet is this is a real driver bug, not backport bug. Can you git clone git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git and use your .config, and build and test that kernel ? If it fails to boot / crash then you know its the driver. Has brcmsmac ever worked for you? Luis
