This patch fixes that. Well I applied your patch without the ones from Thomas Schlichter. Was is intended like that or should it be on top of Thomas patches? I haven't tested thouroughly, but on the first impression your patch didn't make things really better, that's why I stoped testing. I just did following test: Running prime95 as task taking 100% CPU) and started up mozilla and mailer. This took nearly endlessly. Deaktivating ACPI timer and things are fast again, ie. starting mozilla is like no background task is runnig. I dunno if it is a not 100% working patch or if it is Nick's scheduler, which I am using.
