  # There may be a PCI IRQ problem. Go to "common problems" on this page

" My other PCI board always uses the same IRQ as an Adaptec 2940
The preferred solution is to put each device on its own IRQ line. But some
motherboard BIOSes, notably the Intel PR440FX, don't permit this. To use
both at the same time requires a slight modification of the 2940 driver:
remove the SA_INTERRUPT flag to the request_irq() call. This is required
whenever the 2940 driver must share an IRQ with any other device driver.

- if (request_irq(config->irq, aic7xxx_isr, SA_INTERRUPT | SA_SHIRQ,
+ if (request_irq(config->irq, aic7xxx_isr, SA_SHIRQ, "aic7xxx", NULL))"
