What is a point release?

I have a kernel question. With last updates I have 3 kernels 5.4.x
installed and one 5.10.x (kernel-latest). It happens that the
5.4.x-kernels provoque freezes & sponaneous reboots. So I would like to
ask qubes to disregard these (5.4.x) and keep at least two 5.9.x or
5.10.x kernels when upgrading (and maybe some stable 4.x kernel as
backup in case). How can I do that? Cheers. Bernhard

5.4 is a stable kernel series, so if you experience issues, please report them on the github issues list after some trial and erroring on here or the qubes-os forum.

dom0: sudo dnf remove kernel-5.4.x… -y

It will be nice if the next update will come with a 5.6+ kernel(a lot of people are complaining about Nvidia RTX 20xx issues).
