Thanks, but that system was retired for several reasons two weeks ago. The
thermal and performance issues were secondary issues to the mechanical fail=
ure
of the case (multiple cracks most notably to the hinge attachments). The is=
sues
I had with the old unit are not present with the replacement. The P-states =
work
correctly without the fix recently committed to CURRENT. Temperatures remain
reasonable for even very large builds (rust, world).

I might mention that performance and thermal management is very different on
the Alder Lake processor running CURRENT. At this time there is no support =
for
cores with different clock rates and I run with only the 4 P threads to pre=
vent
frequent panics. It's painful to have 8 cores doing nothing.
