I can reproduce this problem here in my t1000.
It looks like some kind of initrd regression.
Looking at the crashes, the kernel seems to be trying
to dereference a physical address when peeking at the
initrd instead of using a virtual one. That's a big
clue.
This patch should fix it:

sparc64: Fix initrd regression.
We die because we forget to convert initrd_start and
initrd_end to virtual addresses.
