I’ve had problems with the 555 driver like KDE’s lock screen would freeze for up to 30 seconds whilst trying to unlock and resuming from suspend resulted in a black screen.
Please note this is just a dump of RPMs/SRPMs and not a repo, so it’s just a stop gap until 560 arrives and (hopefully) fixes my issues.
You will probably have to fight dnf a bit to get it to actually replace the 555 RPMs, but I’ve not had a recurrence and the akmod dance works just as jankily well as before.
