I don't remember my trac username or I'd reply to this there. Could somebody please look it up for me?

(IRQ is disabled by default on the KM400 and K8M800 chipsets.) I'd try fiddling with BIOS IRQ-allocating settings and booting with various pci= kernel command line options before using DisableIRQ. It's worth checking dmesg for any suggestions, or try pci=noacpi or pci=routeirq or pci=biosirq or others mentioned in linux/Documentation/kernel-parameters.txt Cheers, John. _______________________________________________ openchrome-users mailing list [email protected] http://wiki.openchrome.org/mailman/listinfo/openchrome-users Main page: http://www.openchrome.org Wiki: http://wiki.openchrome.org User Forum: http://wiki.openchrome.org/tikiwiki/tiki-view_forum.php?forumId=1
