After the most recent update, machine hangs up

Hi

A couple of days ago Ive decided to update all three computers: laptop, home and work desktops. The work desktop and laptop got updated to the latest and booted up with no issues. The home machine update went less successfully.

The machine boots up and hangs somewhere around mounting volumes (/root, swap, home, etc)...

My next step is go LIVE boot and downgrade kernel.

Any other suggestions on how to get this machine back online?

Thanks

OB

I had the same issue after the recent systemd update. Failed to mount root partition (timeout after 90sec).

Downgraded all systemd packages to the previous version and it works again. Not sure why it only happens to a few installs. Do you use the systemd hook in mkinitcpio.conf like me?

I doubt Ive added a hook into systemd on this particular machine. Maybe others... have you just downgraded systemd or kernel too? What are you using systemd hooks for?

thanks

Re: After the most recent update, machine hangs up

Here what I did to solve this issue .. at least temporarily

1) boot live iso
2) mount corresponding devices under /mnt/root /mnt/root/boot /mnt/root/var/
3) # archlinux-chroot
4) downgrade systemd and systemd-[related packages] - this step DID NOT help, when rebooted system still had troubles mount /boot
5) downgraded linux-firmware and linux-firmware-whence - this DID SOLVE the problem, and I was able to boot back the system.

So i reverted to the old version 20230404:
==> Software upgrade (new version) :
core/linux-firmware        20230404.2e92a49f-1 -> 20230625.ee91452d-4
core/linux-firmware-whence 20230404.2e92a49f-1 -> 20230625.ee91452d-4
core/systemd               253.5-2             -> 253.6-2
core/systemd-libs          253.5-2             -> 253.6-2
core/systemd-sysvcompat    253.5-2             -> 253.6-2

Interesting. No I just downgraded systemd, systemd-* and lib32-systemd, not the kernel or firmware. The systemd hook I use for discoverable partitions (no root= kernel parameter needed with the correct partition type). I also tested with a root=UUID=... parameter before downgrading which didn't work either.

Re: After the most recent update, machine hangs up

I've discovered one SMALL detail...

My /etc/pacman.conf had IgnorePkg = linux, which obviously prevented this machine from getting the latest kernel. I've commented out the line and updated the kernel and firmware packages too. Booted the machine w/no issue.

The lesson - don't ignore and forget.
