John,

I just tried your latest patchset on an API UP1000.
(MD5 (alpha.ithreads.patch) = 11d809b59741189c7261be15166e2519)


It locks solid after printing the copyright:

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

Config file is basically generic, plus static hints, plus your
