I keep having problems upgrading from Fedora 31 to 32.
dnf system-upgrade download --releasever=32 goes fine, but then when I do the upgrade-reboot, it always freezes up about 1/4 to 1/3 of the way through the upgrade process. The system ends up unbootable and I have to restore the drive from a backup image. I used F11 to switch to console to see where exactly it goes wrong. Several times the cursor simply stopped flashing and the system becomes unresponsive; another time the keyboard buttons worked, but the upgrade process was stopped and showing a “soft lockup” message that kept repeating every few minutes like in the picture. It stops at different packages.
I get these lockups or full-out system freezes occasionally in normal OS operation, maybe once a week or so. I’ve searched the web and I’ve found a discussion where someone blamed it on nouveau and installed
xorg-x11-drv-nvidia, but when I did that and restarted the PC, it would freeze at boot, so I had to restore the image again.
FWIW I have a NVIDIA card, use X11 and appear to be using nouveau. Several years ago I had GPU problems and had to switch from nouveau to nvidia or the other way around (don’t remember). I also repartitioned the drive to GPT with EFI partition a year or two ago and got Fedora to boot again without reinstalling it. This was all long before the last successful upgrade (F30 => F31) about 6 months ago.
If it matters, the upgrade process needed about 7 GB free space, and I made 10 GB, but the last 3.5 GB was by deleting
