I’m posting HCL report for my computer with this ASRock B550 Phantom Gaming 4/ac and Ryzen 7 5800X. I’ve few comments:
- You need to configure the MoBo, most notably to enable the IOMMU.
- The installer 4.0.4 boot shows blank screen after “Xen is relinquishing VGA console” or something similar. (I had a very small time to read it.) In the nutshell, the solution was UEFI Troubleshooting | Qubes OS , but the Qubes 4.0.4 installer seems to have immutable filesystem, so I’ve adjusted the iso file by sed. Note that there are two occurrences of both strings, I have no idea why.
Suspend to RAM: Does not resume, no idea why. I have suspected it to be related to smt=off (see https://www.pcgamer.com/amd-is-analyzing-usb-disconnect-issue-in-500-series-motherboards/ ), but it seems to behave the same even with smt=on. Using kernel 5.10 did not help.
Sound: The card does not seem to be recognized, so I can just use the DisplayPort sound output and no sound input Also, the sound output is not very good (voices are relatively quiet), but there can be multiple components to blame.
- Two controllers. Great.
- One of the controllers does not accept my trackball - it periodically reconnects in very short intervals and cannot be used. Note that this might be unrelated to Qubes OS: https://www.pcgamer.com/amd-is-analyzing-usb-disconnect-issue-in-500-series-motherboards/
LAN: not tested
TPM: The report shows no TPM. However, there is some TPM configuration in BIOS, and it is off by default. I could try to configure it and it might work.
Other issues: Cannot update the Fedora 32 template. I have found some other users with this issue in some other apps running on AMD CPU, but no solution. However, installing Fedora 33 helps. The error in Fedora 32:
$ sudo dnf update
Error: random_device: rdrand failed
Short reasoning why I decided for this MoBo: ECC support for a good price. ASrock’s quality is reportedly comparable to ASUS, and those vendors are the only two who have ECC support on a non-server board. Also, the I’ve seen rather compatible ASrock MoBos in the Qubes HCL.
