Frequent ~24h: BUG: soft lockup - CPU#XX stuck for 23s! [kworker/17:2:11758]

Asked by Brad Krane

I have a frequent CPU lockup issue it affects a random CPU core but does so roughly every 24 hour or so. I have to hard power off the system to recover and it will occur when in heavy use or at idle with Firefox and terminal processes running.

I suspect this is either BIOS issue but have not yet ruled out software by using different OS to see if the issue occurs as well which I should get to in the next week or 2.

System specifics:
Ryzen 9 5900X Vermer
x570 AORUS ELITE rev 1.0 F35 << latest firmware
RAM&CPU combo on QVL

For my future troubleshooting I'll also do the TS step below but I don't have the time available to do so atm so probably a week or two or three

Finally, it's critical to also make sure to test the latest development Ubuntu kernel version as well as the latest upstream mainline kernel.

What else can I do to help RCA this?

Thanks!

Cheers,
Brad
