The fb layer locking was broken. I posted patches early December which should have fixed the ones we know about. ('fb: Rework locking to fix lock ordering on takeover').That patch causes compile errors with "allmodconfig": ERROR: "do_take_over_console" [drivers/video/console/fbcon.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 make: *** Waiting for unfinished jobs.... Hmm?
I have a couple of fixes against fb-rework-locking-to-fix-lock-ordering-on-takeover.patch: http://ozlabs.org/~akpm/mmots/broken-out/fb-rework-locking-to-fix-lock-ordering-on-takeover-fix.patch http://ozlabs.org/~akpm/mmots/broken-out/fb-rework-locking-to-fix-lock-ordering-on-takeover-fix-2.patch Florian has been busy for a month or two - I've been waiting for him to reappear to consider this patch.
