>Description:
I have an external raid controller/array that I'm connecting to 2 Dell Poweredge 2450's with Adaptech 2940 U2W controllers.  Channel 2 of the raid array is mapped to logical drive 0 on id 8, and channel 3 of the raid array (4 channels 0-contoller cache, 1 drive array, 2 host 1, 3 host 2) is mapped to logical drive 1 on id 10.  The first host will boot fine when connected to channel 2, but the second host will fail when connected to channel 3 of the raid array.  I get the following error after hitting F1 FreeBSD (FreeBSD boot manager):

int=00000000 err=00000000 efl=00030246 eip=00001654
eax=00000000 ebx=0000038e ecx=00000000 edx=00000000
esi=00009d3e edi=00001a3e ebp=00000396 esp=0000038a
cs=ce00 ds=0040 es=9d3e fs=0000 gs=0000 ss=9d3e

ss:esp=00 00 3f 00 00 00 00 00-00 00 02 00 df 09 00 ce
BTX HALTED

If i switch the cables (channel 2 to host 2, channel 3 to host 1) which ever host that is connected to channel 3 dumps that error message.  

I've checked cables, termination, adaptec bios settings, etc.

This configuration was tested under winNT 4.0 and Solaris 2.8. 

The kernel is stable, however I did not build world, so BTX is release.
