This is a problem with one of the 8520 I/O chips.  The Amiga's power-on
self-test does not check if all the timers operate.  Commodore's
final production line test might not either.

Swap these chips, and if your problem changes to, say , the keyboard
locking up, then you have your problem.  Replace the bad chip.

If this is *not* the problem, then there are two separate sets of
problems that produce the exact same results.
