    Maybe that's it.

    I ask the card which interrupt line it was given at boot-time:

    pci_read_config_byte(dev, PCI_INTERRUPT_LINE,

    Then I request an IRQ:

    request_irq(softp->interrupt_line, sseintr,
    SA_INTERRUPT, "sse", softp);

    I don't know who exactly is assigning IRQ 217, and I don't know
    where I could read that value.

    Are you suggesting I should call request_irq(217, sseintr,
    SA_INTERRUPT, "sse", softp);

    Maybe you are on to the problem.

    I found out that if I boot with "pci-noapic" that everyting
    works on the Sun machine!!!
