- Allow to tune request_irq() flags from the boot command line using
ncr53c8xx=irqm:??, as follows:
a) If bit 0x10 is set in irqm, SA_SHIRQ flag is not used.
b) If bit 0x20 is set in irqm, SA_INTERRUPT flag is not used.
By default the driver uses both SA_SHIRQ and SA_INTERRUPT.
a) If bit 0x10 is set in irqm, IRQF_SHARED flag is not used.
b) If bit 0x20 is set in irqm, IRQF_DISABLED flag is not used.
By default the driver uses both IRQF_SHARED and IRQF_DISABLED.
Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by
a 53C8XX adapter and a network board.
- Tiny mispelling fixed (ABORT instead of ABRT). Was fortunately

When an IRQ is shared by devices that are handled by different drivers, it
may happen that one driver complains about the request of the IRQ having
failed. Inder Linux-2.0, this may be due to one driver having requested the
IRQ using the SA_INTERRUPT flag but some other having requested the same IRQ

By default, the ncr53c8xx and sym53c8xx drivers request IRQs with both the

If this does not fix the problem, then you may want to check how all other
drivers are requesting the IRQ and report the problem. Note that if at least
a single driver does not request the IRQ with the SA_SHIRQ flag (share IRQ),
a single driver does not request the IRQ with the IRQF_SHARED flag (share IRQ),
then the request of the IRQ obviously will not succeed for all the drivers.
