On the Ryzen 7900X machine, I even saw a crash and kernel trace once when starting the installer. It didn't show up again after a reset and cold boot of the VM :-/ On 6/1/23 18:00, Fiona Ebner wrote: > Am 01.06.23 um 14:02 schrieb Eneko Lacunza: >> Hi, >> >> We have Ryzen 1700, 2600X, 3700 and 5950X machines here, I can test on >> them if that helps (please detail tests to perform). >> >> Thanks >> > > Hi, > thank you for the offer.
