 From the timestamp, no other related messages around that warning.

The CPU is Ryzen 5900X, no OC or whatever, with 16Gx2 DDR4 3200 RAM.

Recently I'm experiencing a lot of random crash, system hangs, user
space app (mostly proton/wine games) crashs, and have already set up
netconsole to catch the dying message, but to my surprise, no more crash
yet but the above warning caught my eyes.

Is this a known problem related to the specific CPU?
And would it be related to the frequent crash I experienced recently?

Thanks,
Qu
