Fixing kernel error AMD-Vi IO_PAGE_FAULT – Linux

Without any clear reason, today an error appeared on my home server, in fact the server crashed and did not respond to any commands, the only option was the hardware reset, from the button!

The server is a HTPC, with remote access (headless server), based on a Ryzen 2400G processor, 16GB Ram, 1xNVMe, 1xSSD, 4xHDDs and a GeForce® GTX 1050 Ti video card, used for transcoding and internet access through two providers, 100 + 1000Mbps. It ran non-stop for almost 4 years, I only stopped it manually, to add / change HDD, video card, network, etc. and is ensured that it stays ON all the time, using a UPS with an autonomy of approximately 12 hours.

After rebooting, I checked the logs and found the following errors:

I searched online for a solution and apparently there is no simple one, but in the end someone specified (via bugzilla in 2019) that in kernel version 5.5 the problem would no longer exist, so I didn’t stop to think and upgraded to the kernel (5.5.0) and I hope that I got rid of the problem!
