Peter,
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, &softp->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!!!
