Hi, In first thread of this issue in LKML, some months ago, (right now, I don't have the link). After some discussion, someone arrive the conclusion of that: You only need this quirks, if interrupts are in XT-PIC mode and is harmless if don't (and "should only run for VIA southbridges"). So if you are in XT-PIC mode, it is more probability that patch -R in question, have some affect. cat /proc/interrupts give you: IO-APIC-... or XT-PIC ? and what PCI_IDs do you have ? (lspci -n) Other issue, you can't revert this patch cleanly because after that we have other patch that adds some more IDs. So just delete any declare of PCI_DEVICE_ID_VIA_82C... and add one declare with PCI_ANY_ID Thanks, Sérgio M. B.
