Hello Dominik, thanks for clarifying! I successfully bisected the commit on the following source "https://github.com/SUSE/kernel". The commit header looks as follows: commit 081d038020fa8cefe6d52e6b48464638c3d62fd3 (HEAD) Author: Hannes Reinecke <hare@suse.de> Date: Fri Sep 11 15:22:13 2020 +0200 block: simplify set_init_blocksize (bsc#1175995,jsc#SLE-15608). suse-commit: 9020cc3ae7e79442df2836058b47ca1fe21ea772 I have a further question: Will the fix be applied to Leap 15.3 or do we have to build our kernel? Thank you!
