4.8.0-rc1: Invalid memory access at $SRR0: 0140f86c $SRR1: 00003030

[Christian Kujau]

Hi,

while trying to upgrade this PowerBook G4 from 4.7-rc7 to 4.8-rc1, it's 
unable to boot the Yaboot (v1.3.16 from Debian/stable) boot loader:

 ok

================================================================

Going back to 4.7-rc7 (w/o installing Yaboot again) works just fine. The 
config is mostly the same (used "make oldconfig" from 4.7), but I've said 
YES to CONFIG_SLAB_FREELIST_RANDOM - could this be causing the boot 
failure? Full .config and screen shot: http://nerdbynature.de/bits/4.8.0-rc1/

Thanks,
Christian.
