I don't have problems with the network. If there's no disk activity on both
disks at the same time, my Amiga gets uptimes of 14 days.

Maybe it's just not noticeable on faster machines? Well, I'm happy I finally
found a way to reproduce the problem :-)

I'm no timer_list expert. It could be some weird thing the IDE driver is doing,
but I can't find it. At least timer functions being called to early smells like
a more generic bug.

At first sight run_timer_list() looks fine in sched.S. The question is: is that
the problem module?
