Some types of Compaq try to assign PCI devices to IRQ 11 by
default. This causes problems when a driver (such as the
TLAN network driver) tries to reserve an IRQ without the
SA_INTERRUPT flag when another driver (such as the aic7xxx
SCSI driver) has already reserved the IRQ with the
SA_INTERRUPT flag.
I've noticed that almost all the network drivers do not use
the SA_INTERRUPT flag, and almost all the SCSI drivers do.
Is there a reason for this? What are the tradeoffs of using
SA_INTERRUPT?
Thanks,
James
