Comment # 8 on bug 1177707 from teo teo

Sorry (not my fault actually) but the comment was submitted before I finished
writing (I went to edit a typo in the subject of the issue, and that submitted
the unfinished comment too).

What I meant to ask was: how do I prevent the next updates from installing the
broken amdgpu driver or whatever it is again, and ensure the working one is
kept? Obviously I don't want to hold all system updates of everything, and
remain stuck forever with today's version of every software on my system.
