Speaking of firmware-related issues, TSC is broken on my laptop, causing reliance on HPET as clocksource and increased scheduling latency. Unless I = have no idea what I'm talking about, I think it's a BIOS issue as well. I made a post on the Lenovo Linux forum about it that I'll post here for visibility: https://forums.lenovo.com/t5/Other-Linux-Discussions/1-second-TSC-warp-on-I= deaPad-5-2-in-1-14AHP9-due-to-bad-initialization-in-BIOS-forces-HPET-fallba= ck/m-p/10021248 --=20 You may reply to this email to add a comment.
