I've recently experienced a number of errors in my proxmox server related to the NVME drives. Thousands and thousands of these warnings.

After looking into this. I've found a series of articles and posts about this issue:
and sadly none of these posts seem to have a solid answer.... and even worse, most replies are just telling people to silence the errors, or even disabling the error recovery features entirely (Absolutely bonkers).

My guess...

For my server, I've found this issue is almost entirely related to the NVME drives overheating.. I've installed some thin heatsinks, and the issue has almost completely resolved itself. (So far multiple hours with only one or two of these warnings)

I cannot confirm if this is true for the others... but I've got a feeling it's the root cause for my server considering how hot these NVME storage devices are getting on GEN 4 / GEN 5.

Anybody know how to read the errors and find if this is reporting anything related to overheating?
