Thanks for the reply. Unfortunately that isn't an option for me (unless 2.6.12.6 supports it, which I don't think it does); the 2.6.1[34] series are badly broken on this box; disk response is x100 slower. The problem seems to be in the acpi subsystem, but I'm not sure. It's been reported on this list, on the linux-ide list and most recently at bugzilla.kernel.org [Bug 5594]; so far nobody has come up with a workable fix or diagnosis (there was a suggestion about the default IRQ used for ide, but I couldn't find where that was set in the kernel [I've never hacked the kernel]).
