Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx vesafb: probe of vesafb0 failed with error -6 NET: Registered protocol family 1 SCSI subsystem initialized libata version 1.10 loaded. sata_via version 1.0 ACPI: PCI interrupt 0000:00:0f.0[B] -> GSI 20 (level, low) -> IRQ 169 sata_via(0000:00:0f.0): routed to hard irq line 11 ... That's all. One thing is pretty strange though which would support your guess with the BIOS problem: I modified the Debian initrd system to forcefully load the via82cxxx module before the libata and sata_via driver but it still does not work, so at least it doesn't seem to be the order in which the drivers are loaded. One other thing I find somewhat irritating is that the driver and the PCI setup disagree about the IRQ assignment: 0000:00:0f.1 IDE interface: VIA Technologies, Inc.
