I have not seen it before, this includes 4.6.0 4.6.0-08907-g7639dad
4.7.0-rc1-00094-g6b15d66 4.7.0-rc4-00014-g67016f6.
It is not reproducible, did not appear on next reboot of the same
kernel.

mine T5120 boots ok 4.7.0-rc6, rootfs being on ext4 .

My T5120 and many other sparc64 machines also boot fine, most of them
using ext4, others ext3 with ext4 driver.
However, I also got a very similar oops from T1000:

This time I got similar (but with slightly different virtual address)
one on the same t2000 on 4.7.0-07753-gc9b95e5. Looks like pointer
