Sounds like on the bad system ztdummy is not getting nay interrupts.

Try running zttest on each system and see what it shows. Also check
the output of "cat /proc/interrupts" on each system. You should have
an entry for "rtc" counting up at about 1024 per second.

ztdummy and zaptel should be loaded and running for the above tests.

What is the make and model of each PC?
