BTW, you could add a test and printk in do_page_fault on address 0x000000f0.
if that ever hits there is a problem with dcbX fixup.

It doesn't get any 0xf0 faults.

FWIW, I'm not seeing the segfault any more, but I still get the lockup.

After that you could stick a
 b DataAccess

 directly in the DTLB error handler to skip and dcbX fixups.
