[Fixed] linux-zen-6.3.5-1 / error messages regarding encrypted swap

Fixed with kernel 6.3.5-zen2-1-zen

Original post:

Since installing kernel 6.3.5-zen1-1-zen I get error messages during boot regarding a failed dependency (/dev/urandom) for my encrypted swap device. Swap gets enabled later during boot anyway. This behavior is new with kernel 6.3.5 and does not happen if I downgrade to 6.3.4.

(edit: with vanilla linux 6.3.5-arch1-1 the problem does not occur. It seems specific to the 6.3.5-zen1-1-zen kernel)

Re: [Fixed] linux-zen-6.3.5-1 / error messages regarding encrypted swap

I have a similar problem:

Failed to start Cryptography Setup for root
and etc

Some changes were done in linux-zen 6.3.4.zen2 which make the whole system unbootable.

linux-zen 6.3.4.zen1 works fine.
