It's an alarming situation that the first question that came to my mind after reading this piece of news was not "what bugs were fixed", but "how bad is the performance impact".

Yeah, maybe you should review your priorities.

It's really annoying that there are no good or none at all changelogs for this stuff - microcode, Agesa, BIOS updates. I'm getting more and more angry at those crappy manufacturers.
Unfortunately there doesn't seem a solution for these problems for consumers :-( I'd gladly pay 100 €$ more for a motherboard that is well supported on Linux (open spec sheets, no ACPI conflicts, coreboot support, good changelogs, ...), but nobody offers such stuff.

Quite embarrassing that AMD haven't published any change log. 👎

To be fair, when AMD and intel release these CPU updates, they are not released to end users. They are released to the OEM's that make the motherboards and BIOS implementations. Whether or not the system/mobo manufacturer publishes a change log is up to them, although there may be NDA's involved so their hands may be tied in this regard.

I hear you...i so much hear you...
It really is a scandal that so much blobs are needed to use modern hardware properly
