keep in mind this is the output from the working non smp kernel.
>Description:
machine works fine with generic kernel.  When I reboot after compiling a new kernel with SMP support the root device fails to mount.  At the "Waiting 15 seconds for scsi devices to settle"   a few seconds will pass then I get simular output to this:

(noperiph:ahc0:0:-1-1)SCSI bus reset delivered SCBs aborted
SMP APCPU#1 LAUNCHED
SMP CPU1 apic initialized
lint0:0x00010700
lint1:0x00010400
TPR 0x00000010 SRV0x000001ff
(probe0:ahc0:0:0:0): timedout SCP handled by another timeout.

and more of the same output till final the system reboots itself.  

the machine is a dual pentium pro 200 on a tyan tiger mb.  
SCSI card is a 2940UW2 160

>How-To-Repeat:
boot the machine with any kernel with SMP support.
I've built smp kernels with may different configs,  last effort I only added smp support and left the rest generic.  None of them will boot it seems.  
>Fix:
I know of no fix.  I've been looking for others having the same problem for awhile now.
