John,
I just tried your latest patchset on an API UP1000.
(MD5 (alpha.ithreads.patch) = 11d809b59741189c7261be15166e2519)
It locks solid after printing the copyright:
FreeBSD/alpha SRM disk boot, Revision 0.3

ok boot
Entering kernel.ithreads at 0xfffffc0000330780...

This is with both serial & graphics console.
The UP1000 uses the irongate chipset & routes all interrupts through
isa. I tried adding an isa_{dis,en}able_intr() functions and
replacing the enable/disable args to alpha_setup_intr() in
isa_setup_intr(), but it didn't seem to have any affect. The box
doesn't have a halt switch, so I cannot determine exacly where it is
locking up.
Do you have any ideas?
Thanks,
Drew
