| I've got a SMP machine with a Supermicro P3TDE6 motherboard.  (Serverworks
| HE-SL chipset, dual 1.26GHz Pentium III's.)
| It boots just fine with a GENERIC -current kernel (sources cvsupped
| yesterday at ~1500 MST), but hangs (at the "Waiting 15 seconds for SCSI
| devices to settle" message) when SMP and APIC_IO are enabled.

I have a similar problem with -current and SMP.
Heavy I/O on the SCSI system (say a buildworld or even an FSCK) causes a hang 
(no panic). I think interrupts go off and stay off.

This happens with both the onboard and UFW PCI card, both Adaptec with ACPI
on and off (it's happened since SMPng started, I figured it was one of those
things that'd get fixed eventually). Although Matt's latest patches make me
think it might be sooner rather than later, so I'll be crash testing again
next weekend methinks.

ahc0: <Adaptec aic7895 Ultra SCSI adapter> port 0xd400-0xd4ff mem 
0xedfee000-0xedfeefff irq 10 at device 9.0 on pci0

0xedfef000-0xedfeffff irq 10 at device 9.1 on pci0
aic7895C: Ultra Wide Channel B, SCSI Id=7, 32/255 SCBs

ahc2: <Adaptec 2940 Ultra SCSI adapter> port 0xd000-0xd0ff mem 0xedfed000-0xedfedfff 
irq 9 at device 15.0 on pci0
aic7880: Ultra Wide Channel A, SCSI Id=7, 16/255 SCBs

I try an SMP kernel about once a month.
