I might had missed something, but did this problem appear when you
installed the GOTEK and was it known to work before you installed the
GOTEK?

If it's not really GOTEK related, it could be some kind of timing issue
related to whatever happens on the (cpu) bus.

Are this revision of Amiga 2000 really known to generally "work"? (Of
course they did work as they were delivered back then, but are various
expansion cards and upgrades known to be compatible)?
