Is it possible to induce a delay in your ISR to allow the thing to complete
the interrupt assertion? Or will you always have this race condition as
long as the hardware is broken?

Subject: [ntdev] RE: ISR gets called although device does not interrup t
Hi Mark,
Yes. I understand that the device must be able to
support shared interrupts. But the person who had
designed this card has not taken care of shared
interrupts and there is no way we can fix the card
now. If I try to read from the status register of the
card while it is in the processing of asserting an
interrupt, the card is left in an invalid state and a
call to READ_REGISTER_ULONG to read the status
register results in the machine freezing. Hence I am
looking for a way to have an exclusive interrupt for
my device. Is there any way to disable ACPI ?
Thanks a lot
Madhu
