Do you have a hint how to debug this? I don't see a link. I'm don't know if there will be another v5.11 release. Could you please check if this problem exists in the latest v5.10 and v5.12? v5.10 will be maintained longer. v5.12 is more or less staging for upstream. Its printk code should be newer compared to v5.11. > Best regards > Uwe Sebastian
