I am having a problem getting APIC_IO working on my Tyan Tomcat III
motherboard with SMP. I originally posted to the smp mailing list and
was advised to also post here (by Steve Passe).
The symptoms are:
with the APIC_IO option enabled, the kernel boots and then stops
never passing control over to init to finish the boot. At this
point I can usually Ctrl-Alt-Del and reboot although once or twice
it actually locked up the computer. (see boot messages at the
bottom of this message)
Without APIC_IO it seems to work ok.
Unfortunately, I don't have another SCSI controller to try.
Any ideas?? Let me know if I forgot to include a necessary piece of info.
Below are various responses from Steve concerning this matter (summary):

as I predicted, it fails to remap the 3940 properly. However it does
appear to leave it at INTs 10 & 9, and INTs 10 & 9 appear to be enabled.
[---- Another message from steve ----]
Might be a missing INT problem. If you can borrow another disk controller
(2940/154x/etc) it would be an interesting experiment. My suspicion is that
the 3940 is not working correctly in this setup.
Unfortunately I don't have alot of time to pursue this right now, I've
got a "real job" that is consumming my time... If anything occurs to me
I'll get back to you. You might also post a summary of the problem and
my suspicions on hackers@freebsd.org. I worked with STefan to get the original
PCI stuff working, he might have insite on the 3940 & PCI.
