AMD Confirms Linux Performance Marginality Problem Affecting Some, Doesn't Affect Epyc / TR

[haagch]

Did you try the AGESA 1.0.0.6B Bios?

No. I have the update installed but I did not try whether it's still happening. But I have seen the other thread where people said they still have it with 1.0.0.6b so I thought I'd just get it replaced instead of having to deal with it.

Do bridgman have an info to share with the forum for whether there is a CPU microcode update that fixes the problem?

I am not aware of a microcode update (or AGESA update in general) which addresses the segfault issue.

There are other issues being fixed in each new update though.
