2.1.123 SMP Problems

I've got an Acer Altos 7000/p with a 3c590. Tried to upgrade to 2.1.123
with SMP enabled and everything LOOKS ok but the network card does not
respond (EISA bus system, PCI network card). (ifconfig shows it OK...you
can ping localhost but nothing outside).
Also, if I enable the SCSI interface (AIC-7870) it does not work either
(SCSI bus timeouts indicate IRQs aren't being served).

Disabling SMP in the Makefile makes everything (eth0 and SCSI) work OK.

The /proc/interrupts from SMP looks like:
15: 556145 XT-PIC 3c590 Vortex 10Mbps

For Non-SMP /proc/interrupts looks like:
15: 15886 XT-PIC eth0

Under SMP though, the "ifconfig" does NOT show as many interrupts as
/proc/interrupts -- so maybe the interrupts aren't being mapped correctly?

The SMP boot messages are:
