Hello
After a system crash and hard reboot, when I reboot on any kernel, my machine eventually goes into rescue mode, following errors around LSPCON.
Any ideas how to resolve this issue please?
A google search: Google Search shows plenty of people with similar lspcon messages, but that has nothing to do with your problem it seems - the Arch forums suggest it was intermittent depending on what kernel was being used, but the system still worked.
I expect your problem is something else, perhaps you need to run fsck on your filesystems? Although the real question it what caused the system crash? And is your hardware stable? New or old?
I had a blackmagic external video card plugged in via TB4 . On shutting down, the OS got stuck on a black screen so I pulled out the tb cable, which let the os shutdown. On reboot, I get this error.
Clearly pulling the cable was not such a good idea.
Are you able to use a different video card than this external blackmagic one? Is there an onboard graphics? Just want to see if it will boot when that card is no longer connected to the computer.
The boot crash is the same on all kernels and if the box is connected or not. It has a driver so , I tried to uninstall them, but the system tells me they are not installed when I try to erase them and already installed when I try to install them
I get the impression that due to the crash, the LSPCON port d thinks it’s still connected to something it can’t find. Is there a config file for this sort of thing?
Managed to do a dnf update. The lspcon error is still there but the boot now crashes out after
openssh server daemon. Could there be a correlation?
OpenSSH started OK, it’s more likely to be whatever comes after it - although we cannot see what that is. I don’t know whether systemd-analyze dump could help or not. For example, boot into recovery and mount the disk partitions, chroot into them and then see if that command could give an idea as to what comes next.
I decided to rebuild the machine from scratch.
Stangely, when booting from the USB, I got the LSPCON error.
The new build still has the LSPCON init failed on port d errors but it no longer crashes. The Dell USBC port that was connected to the video card work.
But the HDMI circuit no longer works (I read somewhere that LSPCON init failed is connected to HDMI).
Following the suggestions below:

I got the hdmi back.
