linux-image-2.6.28-13-generic stops loading if selinux enabled

[damon raphael]

Ubuntu 9.04 (Jaunty ) working OK after online upgrade from Intrepid. 2-3 days ago a recommend upgrade was accepted and this new kernel was installed. The boot process stops a few seconds after the splash screen appears.
I edited grub to remove "splash".
Kernel panic occurs on the 2nd page:
avc_has_perm_noaudit+0x186/0x1b0 SS:ESP 0068:c072bc14
Kernel panic-not syncing Fatal exception in interrupt

If I boot from the "recovery" line of grub for this kernel and choose the 1st option "Continue with normal boot" the boot process continues perfectly.

Rebooting and selecting the "normal" - top line 2.6.28-13-generic boot:
I edited grub and changed SELINUX=1 to SELINUX=0 which I presume disables SELINUX. The boot process progresses normally.

Is this due to a conflict between AppArmor and Selinux? Does one or the other have to be disabled?

[chuckr (chuckrister)]

AppArmor and SElinux both do the same thing. Try to disable AppArmor and see if that helps solve problem.

[damon raphael (w7md)]

The default is: apparmor.enabled=0 selinux=1 which "stops loading"

The following option combos boot OK:

apparmor.enabled=1 selinux=0

AND

apparmor.enable=0 selinux=0

This kernel, at least on my machine, does not run SELINUX. I will enable apparmor and will not attempt to remove SELINUX.
