Hardware problem, most likely bad memory:

That's the single most common oops footprint pointing to bad memory: an
error in get_hash_table, with a single-bit flipped in one of the
registers (%edx=0x10000000) and a paging error trying to reference that
as a struct (virtual address 0x10000004).  Your first port of call here
is memtest86.

Cheers,
