Hi Hauke !

Thank for the boot log. So our decision for this years upgrade to stick with

older EPYCs was right from the risk point of view.

The panic looks like an issue with the cyrpto code and is probably worth 
a PR


unless someone looking here has a fix. I am still collecting what if needed

to stall a xen vm to death with ZFS backup, pg_dump to ZFS and large java

processes.

Thanks

  Frank

Since you asked:

Epyc 9554P (64c) on Gigabyte R263-Z70 board


This is one of two machines that will eventually run Arch Linux for
Matlab and python numerical simulations. If you have any fixes to try
out in the next couple weeks, I will be able to do that.

Cheerio,

No worries- I got information from Hauke in the mean time.

Ah, yes, I should have checked better, it would have been a milan cpu so
a Zen3.

The new pkgbuilder is Zen3, so still too old.

Re: Experience with Epyc 8/9004 series CPUs?

Hi Brett !

Thanks for that data point. We are currently running EPYC 7xx2 (Zen2) 
CPUs successfully on


SuperMicro boards 16C/32T and 512Gb for several years now.

As you said a "couple of years ago" I assume those CPUs where not 
Zen4-architecture.


According to AMDs website general availability for EPYC Zen4 was 
announced 2022-11-10.


So they are fairly new, that's why I am asking whether anybody has 
booted those. A common


shortfall in the past was temperature sensor support for a while.

Best regards

  Frank

A couple of years ago I booted a NetBSD-current on a 64 core Epyc with
either 128gb or 256Gb of memory.  It booted fine, the only bummer is the
server I had contained an unsupported raid controller so I couldn't see
the disks at all.
