I think it's fixed in 2.6.16-rc1-mm2. In fact a whole boatload of problems I was having are fixed in this -mm release, including a nasty libata oops that seemed to have a few people scratching their heads. I've now done in excess of 20 reboots with this code and haven't had either problem show up at all. So for now I'll keep a record of things for a bit longer, but I guess I've reason to be fairly confident that both this USB/IRQ problem and my ATA/IRQ problem are now fixed. It does make me wonder if the ACPI update in rc1-mm2 fixed it, and was actually the cause of most of my problems......it would be nice to know for sure. Thanks, Reuben
