2.6.36-rc7: kernel panic with SECURITY_TOMOYO=y

[Christian Kujau]

Hi,

I wanted to test Tomoyo, so I enabled CONFIG_SECURITY_TOMOYO in my 
.config, wich enabled also:

+CONFIG_SECURITY=y
+CONFIG_SECURITYFS=y
+CONFIG_SECURITY_PATH=y
+CONFIG_SECURITY_TOMOYO=y

However, during boot the machine (PowerPC G4, 32 bit) now panics:

I don't have a serial console, so I ran the image of the oops through some 
OCR converter:

Kernel panic - not syncing: Profile uersion 0 is not supported

(Don't trust the numbers in the first two rows though (the ones in "[]" 
brackets) the other ones should be fine)

I've not bisected the issue yet (compiling one kernel takes about ~40min 
on this box), any ideas what might have caused this?

Christian.
