I have one of these X8DT6 systems. It has grub2 as the primary boot
loader which then loads zfsloader. Many weeks back I updated the BIOS,
grub, and FreeBSD and ran into a similar problem -- zfsloader would
start, print a few messages, and then the system would reboot. I
tracked it down to the int 0x13 call (with eax=0x4800) in bd_int13probe.
It would walk past the end of the edd_params structure and corrupt the
return address on the stack. I worked around it by padding edd_params.
I was planning to debug it further to find out which of the 3 things
that were updated caused the problem but Other Things(tm) came up. See
if this works for you too:

Navdeep,
I've committed a different antidote for this BIOS bug as r243025.
Could you please that it works for you too?
Yes it works for me too, thanks Andriy!

Navdeep
