Yeah, sorry for the lack of updates, I’m trying work through pain of reboots and loss of work in last days.
As a quick update:
- AMD support talk: Basically AMD said they are ready to RMA the CPU should I choose to do so, but they do not believe it’s the problem, which was also confirmed by swapping the CPU to my wife’s motherboard. The guy I’ve talked to (located in Canada) tried to replicate the problem with Ubuntu 20.10, 5900X and Asus X570 Pro board, but no luck, it was running stable for a week. He said it looks like the problem is with particular motherboard, most likely with power delivery. In addition he confirmed that this error IS NOT with the CPU, this is the even that CPU catches and reports back. The error point to the timeout for the data reception, which is probably caused by slow power state change due to poor power delivery. Current state is: they are waiting for me to exchange the board and report the results.
- MSI ticket was closed for me with a quick suggestion to proceed with RMA, however I need to do it with the store I’ve purchased it, not with MSI directly.
- I’ve talked to the store (I’m located in Germany, but everything slowed down by the fact that my German is not that good just yet) and they obviously need to have a look at motherboard first, so I need to send it for repair and then it would be either repaired or replaced.
- Current status, I had a lot of work and I was moving data to my laptop and just switched today away from the desktop, so I’ll remove the motherboard and will send it back tomorrow.
