Unfortunately, I could not trigger any of those here both in a bare-metal and

The only other thing I can think of is to setup kdump to capture a vmcore when
either GPF or BUG() happens, and then share the vmcore somewhere, so I might
pork around to see where the memory corruption looks like.

Another question that I forgot to ask, what type of device is /dev/sg0 ?
On a prior occasion (KASAN, throw spaghetti ...) it was a SATA device
and the problem was in libata.
