8.0-RC2's /boot/loader doesn't like booting from ZFS?

[Kenneth Vestergaard Schmidt]

Hello.

Two separate machines fail when starting loader(8) after upgrading  
from 8.0-RC1 to -RC2. Both have been installed by following http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot 
  - one is a VMware machine with just one disk, the other a Sun Fire  
X2200 server with 2 disks in a ZFS mirror.

They both booted fine with -RC1, but with -RC2 the last messages are:

   Can't work out which disk we are booting from.
   Guessed BIOS device 0xffffffff not found by probes, defaulting to  
disk0:
   ficl-s not found
   Assertion failed: (FALSE), function ficlCompileSoftCore, file  
softcore.c, line 428.

Reverting to the -RC1 /boot/loader fixes.

Usually the 'Guessed BIOS device' stuff is caused by the loader re-executing
itself, perhaps due to a stack overflow.
