Here are the boot messages: Apr 30 10:13:38 Reineke kernel: puc0: <Moxa Technologies, Smartio C104H/PCI> port 0xa000-0xa00f,0xa400-0xa43f,0xa800-0xa87f irq 19 at device 14.0 on pci0 Apr 30 10:13:38 Reineke kernel: puc0: Reserved 0x40 bytes for rid 0x18 type 4 at 0xa400 Apr 30 10:13:38 Reineke kernel: sio4: <Moxa Technologies, Smartio C104H/PCI> on puc0 Apr 30 10:13:38 Reineke kernel: sio4: type 16550A Apr 30 10:13:38 Reineke kernel: sio4: unable to activate interrupt in fast mode - using normal mode Apr 30 10:13:38 Reineke kernel: sio5: <Moxa Technologies, Smartio C104H/PCI> on puc0 Apr 30 10:13:38 Reineke kernel: sio5: type 16550A Apr 30 10:13:38 Reineke kernel: sio5: unable to activate interrupt in fast mode - using normal mode Apr 30 10:13:38 Reineke kernel: sio6: <Moxa Technologies, Smartio C104H/PCI> on puc0 Apr 30 10:13:38 Reineke kernel: sio6: type 16550A Apr 30 10:13:38 Reineke kernel: sio6: unable to activate interrupt in fast mode - using normal mode Apr 30 10:13:38 Reineke kernel: sio7: <Moxa Technologies, Smartio C104H/PCI> on puc0 Apr 30 10:13:38 Reineke kernel: sio7: type 16550A Apr 30 10:13:38 Reineke kernel: sio7: unable to activate interrupt in fast mode - using normal mode Meanwhile I plugged the Moxa board into another PCI slot of my motherboard and the conflict with the ata6 interrupt seems to be solved. The silo over- flows are still there. By the way: How should I set the BIOS parameters "PCPI 2.0 yes/no" and "ACPI APIC yes/no"? Do they have anything to do with the PCI interrupt behaviour?
