I installed 13.0-RELEASE on a Thinkpad T490, and I saw all of the same symptoms
described by others above. The suggestion of setting
hint.hwpstate_intel.0.disabled=1 fixed it.
I noticed one symptom not mentioned that might be specific to just me. I can
reliably trigger the behavior by moving my laptop, e.g. repositioning it on the
desk, or carrying it from my desk to my armchair. I've heard that Lenovo has
motion-based CPU throttling, so maybe that is related?
