I could not post to the forum.qubes-os.org becuse I am a new user, so I am posting here.
I could not get R4.1 to work so it forced me to install the R4.2 rc5.
I tried the R4.2 latest kernel but had network errors after updating, which is an issue on GitHub. This install is with the default kernel.
I had installer issues with rc5 that the reboot button on install sometimes does not work. And once on boot I got a CPU core locked errors.
I turning off SMT which fixed some installer problems with R4.1 but did not fully fix the installer that hung up polling nvme. It could not load to the install Wizard.
I am unhappy that I can not install the stable version. And wish I could
I have not been using it long. I had tried a previous release on a M6800 but due to hardware limits I could not use the current version and the version that worked is no longer supported. I did not use it for long at the time. I am starting over as a new user.
Everything seems to work for R4.2 on x570 Aorus Extreme v.1.1 with Ryzen 9 5950X and AMD Radeon 5700XT Graphics. I have ECC Corsair memory installed.
