[SOLVED] Updating after a month, major breakage

Hi,

I've been away for a month, and running an update now breaks multiple aspects of my setup.

I ran

sudo pacman -Sy archlinux-keyring && sudo pacman -Su

due to signing issues, and after reboot, the following systems are affected :

* Long delay after Luks password prompt, zram mount fails and waits for timeout
* no trackpad. The mouse icon is displayed on the screen but unresponsive. Keyboard works fine
* iwd is failed and fails subsequently when restarted, no WiFi connection.

I've had breakage before when updating, but nothing that big, and I couldn't easily fix any of the issues. I reverted to a previous Btrfs snapshot, everything working fine. I ran the update again, and everything broke again in the same way.

I don't see any major package update that should cause any breakage;

Any idea where I can start to look ?

thanks !

no trackpad and no wifi makes me think of a kernel mismatch. Is /boot on a separate partition/filesystem/subvol?

Hi, thanks

Yes boot is on separate ESP. Good idea I'm going to investigate that. I set up Secure Boot before going away and everything seemed to be working fine, but maybe I missed something.

I'll report back, thanks !

[edit]

posting relevant journal logs as I find them (nice to have /var/log on a separate subvol !)

Re: [SOLVED] Updating after a month, major breakage

Thanks for the tip ! definitely a kernel mismatch problem, I could see from the logs that the booted kernel was still 5.18.8. Just ran it again and all the mkinitcpio presets seem to be empty, so no image is generated... That should be fixable

[edit]

The culprit was the linux.preset file which had "default_image=" commented out (only building "default_efi_image=". I think I had had applied a patch that made it work like that, but maybe the mkinitcpio update removed it. Or I played with it and forgot to uncomment.

Anyway, thanks very much for pointing in the right direction !
