Is that actually inclued in your bisection? I suppose it is, but it's quite clear that with only 9ea927 you'd get crashes with building it statically. I have no real idea why ieee80211_register_hw() would fail (but then again, I'm a kernel n00b). It's apparently related to doing platform_driver_register() before, so perhaps it's missing another field in the struct. "unable to handle kernel paging request", is that a normal error message if a driver fails to initialize? I would have assumed that the kernel would't panic if a single driver fails to initialize. Or does that mean it actually tries to access uninit'ed memory? I can certainly check out linux-next, build the whole thing statically, and try to twiddle things a bit, but I'm afraid that's just going to take a while (both because this is all new to me and I'm working on other things ATM), so please don't hold your breath. :-) Thanks, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
