Hi!
When I first booted into v6.13 I noticed my laptop got instantly hotter
and battery started draining fast. Today I bisected the kernel an ran
powerstat [1]. It comes down to
Upstream commit: 6b34562f0cfe ("crypto: akcipher - Drop sign/verify operations")
These results are reproducible on my system 100% of the time, and the
regression is still present on the latest upstream commit.
Please tell me if there is more info or test I should provide. I can
test any patch candidates too.
Happy holidays!
