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.
