seems doing a bisect right now during the merge window is breaking,
anyways looking through the commits I think this:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=c53fa1ed92cd671a1dfb1e7569e9ab672612ddc6;hp=06dc94b1ed05f91e246315afeb1c652d6d0dc9ab


might be what I am hitting, causing gdm to die out, as it starts.

any ideas?

not sure if anybody is seeing this or hitting this with the current,
but reverting the above commit does not fix the problem.
will try another bisect(hopefully)

Are you sure it is a kernel issue?  Seems more likely that it would be a
policy problem.  What AVC denials are you getting?



strange.. was not even thinking of the avc's because the policy has already been customized and has been working for a while now without adding any rules.

Anyways your right, seems the labels get changed or something with this kernel or something:
