I have had the same problem with a triton mother board P100, S3-964 video,
and an NCR disk controller.  I swapped out disk controllers with a Adaptec
ISA controller and it still hangs.  I havn't been able to get through a
make world in the src tree since I switched from a 486dx50 - opti chip set
to the 100 mhz pentium with the triton chip set.  It almost seems pci bus
related but I have no idea.  I have now disabled the external cache and I
am trying the make world again...  It is a lot slower...

Is there a method of forcing a crash dump in FreeBSD?  Once I get a hang
I would like to reset and dump the memory to see what it is up to.  Is there
any way of doing this?
