This has been an ongoing thing for me - I've been aware of the problem for some time, but have not had the time to do anything about it. I could sware that 5.0 + ACPI used to work, in fact I might reinstall it to see. I have already tried rebuilding my DSDT, and am going to try some further experiments (the Compaq raw .aml, does not compile cleanly with iasl and needs work). Going to try copying the resource allocation code from a desktop machine that seems ok with ACPI into the laptop (that'll be fun). I may also start walking through the resource allocation/discovery code in the kernel to see what the device driver is doing. My basic premise is that the kernel is having difficulty determining which IRQ to use for the PS/2 mouse. Nate if you have suggestions of things to try I'm perfectly happy to do so. For Nate, my boot -v output is at http://humphrey.dyndns.org/dmesg.boot original disassembled DSDT is at http://humphrey.dyndns.org/presario2100us.asl slightly tweeked (and no doubt munged) version: http://humphrey.dyndns.org/presario2100us2.asl http://humphrey.dynsdns.org/presario2100usdiff Thanks, Brendon
