OK, this line in your oops:

Unable to handle kernel paging request at virtual address 5a5a5a5a

Probably means we hit some slab poison with DEBUG_SLAB set.
Looks like your config boots fine with DEBUG_SLAB disabled
for me.

As this only happens for timer12, I wonder if we're again
hitting some uncompress issue with corrupted dtb. Changing
u-boot ftdaddr higher up might possibly make it go away.
Or else there's a bug elsewhere :)

Tony
