The freezing happen approx once per day, seems more often when connected to my android mobile hotspot (may be unrelated).

"journalctl -p err" gives:

nvme 0000:03:00.0: AER: Error of this Agent is reported first
pcieport 0000:00:02.4: AER: Error of this Agent is reported first

The nvme error, happens approx 10x more often.

I am running a WD_BLACK SN850X 4000GB, Firmware: 624281WD

I tried the WD website to see if there is a FW update, but there are only windows/mac tools and no link directly to the FW (that I could find).

Update: it seems that the updated firmware has solved the issue, I have been running 4 days without a crash. Thanks to @rotopenguin@infosec.pub for pointing me to the Framework guide.....why is this not on the WD website and easy to find.
