I used to have a Q700 on which I tried to run Linux. My Q700 was a
really early
one (bought the moment Quadra's where available in NL) with an early
MC68040. It
seemed the CPU cache had problems. In MacOS you had to disable the CPU
cache with
the cache Control Panel for it to me stable. In Linux it was unstable,
however not in e consistent way as you describe, so maybe this is a
different problem. The problems I where have were regular segfaults etc.
