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?

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