Anyone else you can ping that may know about this and maybe has not seen it yet? They can try to throw their hat in the ring like @Rouge_One or something?That's why I crossed out the cable question. I didn't really think that one through.
There was the earlier Latencymon results pointing towards kernel drivers, but the C drive is an NVMe - that doesn't use any cables.
The friend has similar hardware, but experienced similar symptoms? SUPPOSEDLY, all that's different is the cpu and motherboard... but SUPPOSEDLY, an ex-HDD later, and there's no problems?
IDK... it feels like we're still at step 1...
