Abysmal (< 1 H/s) Hashrate On Linux (5.15) Mint Suddenly

[a-p-jo]

Describe the bug
I am suddenly getting hashrates between 0.63 to 0.74 H/s where I would get 640 to 730 H/s earlier (1000x slower). Initially, it would go away after a few reboots but now it won't.

To Reproduce
Use Linux Mint 21.3 (it ships with kernel 5.15.0-116-generic). My CPU is a i3-6006U, unsure if that matters.

Required data

• XMRig version
  • Latest: https://github.com/MoneroOcean/xmrig/releases/tag/v6.21.3-mo15
  • I also built it myself using the instruction here (https://xmrig.com/docs/miner/build/ubuntu) and the source .zip for release 6.21.3-mo15
