It looks cosmetic, and likely to be fixed, but not really worth worrying about. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=13018 > Subject : 2.6.29 on MacBook 2,1 fails to reboot > Submitter : Trenton Adams <trenton.d.adams@xxxxxxxxx> > Date : 2009-03-30 2:04 (8 days old) > References : http://marc.info/?l=linux-kernel&m=123837870307249&w=4 > Handled-By : "Morten P.D. Stevens" <mstevens@xxxxxxxxxxxxxxxxxxxx> This went through bisection, but looking at the email log, I tend to suspect that maybe Trenton marked some versions good even though they weren't (because they got versions numbers from v2.6.27), and didn't realize that that messes up bisection in a big way. The bug _sounds_ like some deadlock due to lock problems - the shutdown path often triggers locks that no other path really cares about. And we had some lock problems in the sound subsystem that got fixed post-2.6.28, for example. And it looks like the problem is somewhere in sound shutdown: 12181 delete_module("snd_hda_codec", O_RDONLY|O_EXCL) = -1 EAGAIN (Resource temporarily unavailable) <0.000011> So commits like 91054598f794fb5d8a0b1e747ff8e2e8fc2115b3 ("ALSA: pcm_oss, fix locking typo") might explain it.
