Nopes. It makes the UVD errors go away, but the boot still gets stuck at the same point. Everything hangs up, requiring me to do a hard reboot.
Well that the UVD errors go away is already an rather interesting result. Please attach a new dmesg log if possible.
Weirdly, I could not find any errors in either syslog or Xorg, which makes me feel I'm doing something wrong on my side (but I compiled it exactly like in the official repo, with the additional patch).
Your compile is probably working right, but it is possible that we actually see two different problems here.
