In fact BIOS 1705 without any boot option seems
to provide a stable machine (51 hours of stress
test without failure). Plus BIOS 1705 has
an explicit TLB fix auto/enable/disable
that the previous BIOS didn't have (even
if TLB fix was on).

So probably it was probably a BIOS bug, we're continuing
the stress testing.
