[REGRESSION] linux-6.5.8.arch1-1-x86_64 wont boot with LUKS

After upgrading to the kernel 6.5.8 above my machine would not boot with the following error:

ERROR: device '/dev/mapper/cryptroot/' not found. Skipping fsck.
mount /new_root: no filesystem type specified.
You are now being dropped into an emergency shell.
sh: can't access tty; job control turned off
[rootfs ]#

After downgrading the kernel the issue disappeared again.

errors when creating the initramfs that you missed?

I don't think so as a simple downgrade solved the issue. (no change in config)

Any errors, messages beforehand?
https://wiki.archlinux.org/title/Genera … l_messages

Race condition/timeout?
Does using "rootwait" help?

Can you open the crypt device from the current iso (should™ have 6.5.8 by now)?

1. thank you for the bbs tip

2. so far I was unable to collect any more evidences (debug info) as even the temporary tty in which the shell dros

rootfs

the keyboard strikes are not even recognized.

I will try to reproduce the issue from the latest ISO during the next few days (work week will be intense).

if everything else also doesn't work (no keyboard in the emergency shell), it sounds like something went wrong building the initramfs / loading the required modules

you could try the fallback image, or check the initramfs file itself if required modules are in there at all or not

The emergency shell is by default useless…

The downgrade would rebuild the initramfs, so that would fix an error when it was generated on the newer kernel.
