@Pete-S said in Fedora 31 stuck in a boot loop:
Can't provide any input but it's interesting to read the problems that shows up every time there is a new Fedora release out. Your customers are a forgiving bunch for sure.
That said, it's great for the open source community to have lots of people running the latest and greatest.
I've been on Fedora about 2 years on my laptop now and I know exactly what you're talking about.

I don't think @JaredBusch runs gnome, so that probably saves him a lot of grief.

@JaredBusch said in Fedora 31 stuck in a boot loop:
So everything was working this morning.
I shut down and left the site I was at.
Now I am trying to boot up and it simply goes back to bios.
Obviously something is crashing in the boot cycle. But what?
Kernel 5.3.12-300 is current.
But both previous kernels fail also.
5.3.11-300
5.3.8-300What changed? Auto updates, drivers? Update logs?

Ah I didn't see that somehow.

I'll have to check my laptop to compare kernels. Mine won't go to sleep. If I shut the lid and open it again it does a hard reboot instead of resuming from sleep.
-
My desktop has all the same updates applied, but has not been rebooted yet as I was out of town.
I'm home now, and will be able to mess with this. First up, I don't know where to go to look for a log since the thing is not getting to any visible boot state.
The drive appears normal. I put it in a USB housing and copied a few things off, like my SSH identity files.
Otherwise, I'm not worried about losing the information, nothing on my laptop is important, unless saved in my Nextcloud sync folder. But I would prefer to figure out what went wrong.
Obviously not risking a reboot of my desktop right now either. Because while there is no critical data on my desktop not saved elsewhere, the time to resetup my environment and Windows VMs for dev is very unappealing.
-
I did have a Fedora 31 laptop (different model Dell than mine) spun up and logged in two weeks ago. I have ran updates on that one and rebooted. it is running fine.
But it has almost nothing installed. I was only testing some Nextcloud stuff on it.
-
After it fails, doesn't journalctl give any indication of what's causing failures to boot?

it is in a boot loop. there is nothing to see.
if I choose to boot to recovery mode, it drops straight to emergency mode.
journalctl -xb retuns like 1200+ lines. going through that line by line was not something I felt like doing late in the day on Friday after Thanksgiving, while visiting friends.
at a glance it also looked like only the recovery mode boot was in that log.
-
waiting on something to copy off the drive that I cannot find the second copy of. then i'll have it back in my laptop and ready to fuck with.
-
The contents of
/etc/grub.dseem identical on all three systems I have here.- My Desktop - have not tried to reboot
- My Laptop - does not boot
- Spare Laptop - reboots successfully.

Mine goes to sleep when I unplug it from power

Here's an example of my Grub setting using UEFI on Fedora

/boot/grub2/grubenvis a symbolic link to/boot/efi/EFI/fedora/grubenv. Maybe an update to grub screwed up something.
