Should have stepped out of gmail, sorry.] I will certainly take a look. I don't have the hardware, unfortunately. And this is kinda my first rodeo, kernel-wise, so don't let me sound too expert. :) Let me ask a couple questions, anyway. - Later, I'll have time to look for Andrew's message, but do you know -- did he mean an ACPI bug in the firmware, or in Linux? - Does 2.6.38 behave the same as 3.1.5 or the other newest kernels? (If the hardware doesn't require something newer than .38.) There was an IRQ overhaul in 2.6.39, and the two bugs I fixed were regressions from that work. As of now, the bad-irq handling seems equivalent to 2.6.38, but I should make sure that goes for your problem, too. I think I'll cc LKML, too, if you don't mind. I've seen this topic going by, but don't know what's been said. And maybe tomorrow I can get some pondering time - Ed
