I would hazard a guess and say it's broken on the Txx series too -- I've got a T23 that I'm only running -CURRENT on (hence I'm using ACPI, not APM), but enabling ACPI promptly panics the machine. I imagine that if I were to downgrade this system to -STABLE, I'd see the very same things that everyone else is seeing. -- Matt Emmerton "Mark Evenson" <evenson@panix.com> wrote in message news:a0adjwfrkd.fsf@panix3.panix.com... > The following message is a courtesy copy of an article > that has been posted to comp.unix.bsd.freebsd.misc as well. > > Sebastian Benner <benners@bonsai.fernuni-hagen.de> writes: > > > Hi, > > > > I am facing problems with apm on an IBM ThinkPad A30 .
