hi group,

i have to migrate a character device driver for an old synchronus
serial PCI board (Moxa C502/PCI)
from 2.2.something to 2.6.5-smp x86_64.
the problem is, that no interrupts are routed to the driver.
i was able to get interrupts when i used a non-SMP kernel and the
"noapic" boot option.

is there a way to explicitly force the use of the 8259 when i request
an interrupt to get the interrupts for this card not routed via the
APIC?
any pointers are appreciated.

thanks in advance,
dieter
