--- Comment #33 from Toomas Soome <tsoome@freebsd.org> ---
(In reply to spell from comment #32)

Hm. So, enforcing IO size to 1 sector (512B) does not help, but using buffe=
r at
0x8000 does? that is interesting.=20

Btw, did you see comment in bd_io()? It is about proliant and large disk, b=
ut
it *may* explain the randomness factor...

I still wonder if we could determine the size of corruption - note, we can
increase the buffer area in BSS for test purposes.
