it shows, that `acpi_pci_root_create()` takes 82 ms. The 200 ms delay instead
of 100 ms are due to tracing.

[Bug 213031] MEDION notebook internal keyboard not recognized / not working correctly
https://bugzilla.kernel.org/show_bug.cgi?id=213031 --- Comment #138 from dirksche (dirks...@posteo.de) --- Sorry, that I reopen this issue. But I got some more Questions. My machine is the S17405. I'm on Linux Mint and the current LTS kernel is 5.4.0-91. I installed the mainline Kernel 5.15.3 and my keyboard works fine. But my system tell me that linux-headers-5.15.3-051503-generic is broken. How can I find out when the patch will be in the LTS kernel? Or is there another way I can go to? I know that this is not the right place for this question, but I don't know who to ask else. Thanks a lot -- You may reply to this email to add a comment.
