I tried the 2.0.5 Alpha release of FreeBSD on our systems here today
(after building them from the source).  On our 16M P66 machines they work
just fine, but on our 96M P90 system it blows up as soon as it begins to
fsck the disks (usually with a divide by zero error in the kernel although
occasionally I've seen a 'page not present' fault).

Now I had similar problems with the P90 and 2.0R due to a lack of kernel
page tables - the problem was solved by boosting "NKPT".
However, no such fix works here (indeed a look at the code seems to show
that the kernel can magically handle increasing this).  So ... any
helpful hints on what's up would be greatly appreciated.

Thanks in advance

Tim
