On a new motherboard that an existing pair of IDE drives were moved to
I get the following error:


Fatal trap 1: privileged instruction fault while in kernel mode.

frame pointer		= 0x10:0xefbfff50

When booting the FreeBSD 2.2.2 Walnut Creek June 1997 distribution right
after the kernel signs on.  This occurs also with install floppy made from
the CD.

This is a 6x86L-PR200+ Cyrix running at 150Mhz (not overclocked) with 32M 
and 512K cache (tried turing off cache, no change).  I have tried a number 
of bios changes without eliminating the above error.  The same chain of 
IDEs boot Dos/WinfWG (no real test), OS/2, Linux, Win95, and WinNT with 
no problems.  APM is not enabled.  The CPU has a good fan and outlet air 
temp. is 26-28C.  The heatsink on the CPU is only slightly warm to the
touch.
