Things don't work (properly) with acpi=off (jumpy mouse, no network, sound loops). I tried the ubuntu 6.06 2.6.15-23-386 kernel, a vanilla 2.6.17.14 kernel and a xenomai patched 2.6.17.14 kernel. All with same result. So that's reassuring I guess. I recently converted my stuff from RTLinux to Xenomai and just assumed it would be saver to turn off ACPI for real-time operation. Didn't know some systems actually rely on ACPI. > > Jan > > > PS: Please take care to not drop the list from CC. I'm sorry. The mistake occurred to me the moment I clicked send. Theo
