Linux/x86 5.0.21-4-pve Kernel & Linux VM (pvetesting repo)

I confirm that the problem is hardware dependent. All earned only after replacement of iron on the inexpensive server from AMD. In this regard there were questions:
1. Will there be a fix for this problem, or can I already throw away my Intel 771 server?
2. And how are such problems solved with a commercial support subscription?
 
Bugs are normal, especially on the pvetest repository, all will be addressed.

For now, just install 5.3 kernel.
 
I am sorry. I didn't want to offend anyone with my question. This question was born because our management is now considering buying commercial support. In this regard, we need information about it. Is there no such update in the commercial repository, or does production not use such hardware :)

Nobody is offended, no worries :)

The enterprise repository did not has this update, as I've said.

The propagation chain for package update is:

internal developer build -> internal repository -> pvetest repository -> pve-no-subscription -> and only if we did not found any issue until then the package will be moved to pve-enterprise. So it's the most stable and recommended for production use.

The set of different HW and environments tested will get bigger with each propagation, normally most issues are already caught internally or in pvetest, sometimes an issue just did not surfaced there, so the no-subscription repository gets hit.
Hope this clarifies things a bit for you.
