How to debug live CD image?

[Barry Scott]

My desktop PC is happily running Fedora for years.
Its on Fedora 32 now. It also has Windows 10 dual
boot via Grub.

But I cannot boot a live CD image as it gets stuck
in "Monitoring of LVM2 mirrors, ...". This is not a
new problem I have seen this for a couple of Fedora
releases, but not reported it before.

I have tested with both the Workstation image and 
the KDE spin image. Both get stuck at the same place.

How do I go about debugging what is going on?

Can you check latest respins[1]?

Is it possible you don't wait enough, that is about 8 minutes by boot?

Look https://bugzilla.redhat.com/show_bug.cgi?id=1830896

I was introduced to this from eugine in:

It is at 55mins 18s at the moment.

I'll test the respin later and report back.

I use the KDE respin and it hangs at the same place.
I waited over an hour to see if will continue.

How can I help debug this?

I think that your problem is definitely related to this:
https://bugzilla.redhat.com/show_bug.cgi?id=1830896

You can install Fedora and try one of the suggested workarounds.

I have Fedora installed on the HDD of this PC and it boots without any issues.

Its only the live CD that has the issue.

Given that my PC boots from HDD but not live USB image I'm not
so sure that that bug is the problem. Especically if its efivars that are
the root cause as that should be the same for my HDD and USB?
