SOLVED: Kernel 5.11 can't boot luks encrypted root

Hi,

starting with kernel 5.11.1 I can no longer boot my luks encrypted root partition, stalls immediately. No problem with lts-5.10.18.
What did change between 5.10 and 5.11 concerning the boot process?
What can I do to debug it?

Thanks

Hi loqs, thanks!
What I hit was exactly this:
https://bugs.archlinux.org/task/69778
I had more or less the same error message as mentioned in this post.
It is a btrfs error!
Problem solved by solution in said bug report:

btrfs filesystem resize max /

Which gave me in the log:

BTRFS info (device dm-0): resize device /dev/mapper/cryptroot (devid 1) from 1011858014208 to 1011855917056

Booting as expected after this command!
