    No cigar yet. I tried davem's patch first, then yours on top of his. I still get
    both the recursive locking and the kernel warning.

    BTW, wireless doesn't work but if I plug in the wire, then networking is OK. It
    seems to be in mac80211, which is strange because I routinely run the latest
    wireless-testing kernel, and all the wireless bits should be there already.

    I'm still plugging away at the bisection. I think I got away from the kernel
    that won't build.
