What happens is that the IRQs are assigned in a totally other way with 11.0 than with 10.3. Not only via-rhine network card driver also sata IRQs are assigned different. (Here from network card): (11.0): via-rhine.c:v1.10-LK1.4.3 2007-03-06 Written by Donald Becker ACPI: PCI Interrupt 0000:00:12.0[A] -> GSI 23 (level, low) -> IRQ 23 pata_via 0000:00:0f.1: version 0.3.3 ACPI: PCI Interrupt 0000:00:0f.1[A] -> GSI 20 (level, low) -> IRQ 20 (10.3): via-rhine.c:v1.10-LK1.4.3 2007-03-06 Written by Donald Becker ACPI: PCI Interrupt 0000:00:12.0[A] -> GSI 23 (level, low) -> IRQ 20 pata_via 0000:00:0f.1: version 0.3.1 ACPI: PCI Interrupt 0000:00:0f.1[A] -> GSI 20 (level, low) -> IRQ 16 Strange is that I cannot see any warning/error about it. Does pci=noacpi bring up the machine as expected? Maybe acpi_enforce_resources=no helps? If you still have 10.3, one might also want to attach /proc/interrupts of 10.3 and a newer version. Then we see all the IRQ assignment changes. I am still puzzled why the IRQ setup is so totally different. Possibly it's really a "modify chipset settings" command like smbus code be used for? Reconfiguring something on the chipset. I fear the only way to find that out could be a git bisect in the end... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
