No, because nearly every sample has the difference. The tolerance
setting doesn't matter if every sample is mismatched. I don't think
this is the throttling bug. It doesn't match the big description in
https://lore.kernel.org/lkml/20250520181644.2673067-2-kan.liang@linux.intel.com/.

The RHEL kernel has a different naming convention. The -145 refers to
the 145th iteration of the RHEL kernel that started from 6.12 so
6.12.0-145 is relatively new, but I'll build from a new kernel and
test again.
