Doesn't sound familiar.  It's very unlikely to be a hardware problem
because the kernel's timer tick runs off the CPU cycle counter.  Where
did you get the test9 kernel from and what version of the toolchain
was used to compile it?

For A2, turn on the A-step workarounds and nothing else.
For B1, turn on the B-step workarounds and nothing else.

That's real easy: if it's rackmounted, it's a Lion, if it's in a
deskside case, it's a Big Sur.
