[pkg-cryptsetup-devel] Bug#988452: Can't unlock keys with passphrase during boot after upgrade to kernel 5.10.0

[Grzegorz Bizon]

Package: cryptsetup
Version: 2:2.3.5-1

I recently upgraded my Debian workstation and I'm unable to unlock my
partitions during boot. It fails with standard "No key available with
this passphrase".

Using older kernel 4.19.0 works. Before the upgrade kernel 5.3.0
worked fine too. I upgraded 5.3.0 to 5.10.0 and it doesn't work
anymore.

I also upgraded cryptsetup from 2:2.1.0-5+deb10u2 to 2:2.3.5-1.

Other packages:

ii  cryptsetup                            2:2.3.5-1 amd64
ii  cryptsetup-bin                        2:2.3.5-1 amd64
ii  cryptsetup-initramfs                  2:2.3.5-1 all
ii  cryptsetup-run                        2:2.3.5-1 all
ii  libcryptsetup12:amd64                 2:2.3.5-1 amd64


I'm using Debian 10.9 Buster with apt-pinning and just a few packages
from Debian Testing (including kernel 5.10.0).

I will be happy to provide more information if needed.

Thank you!
