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

**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
