I have about 100 Linux boxes (all with the same (binary the same) kernel). Last time I have upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2, .4 and .6) and I have found some problems on VIA based PC's. Probably the reason of this is that some VIA chipsets are unrecognized by IRQ router. In line 586 there is: /* FIXME: add new ones for 8233/5 */ There were only a few of chipsets ID's there, some of my VIA chipsets were not present and kernel used default IRQ router. I have added three entries, so that the code looks like: case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: case PCI_DEVICE_ID_VIA_8233A: case PCI_DEVICE_ID_VIA_8235: case PCI_DEVICE_ID_VIA_8237: case PCI_DEVICE_ID_VIA_8237_SATA: /* FIXME: add new ones for 8233/5 */ r->name = "VIA"; r->get = pirq_via_get; r->set = pirq_via_set; return 1; } The kernel goes fine but I haven't testes it for weeks, I'm just a moment after reboot :) One thing is different (better?): Using previus kernel I had: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0 now I have: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11 Maybe it is good idea to add there some more VIA chipsets? The ones I have added seem to be OK.
