But the good news: I don't know what I changed, which was relevant after I committed the bug. But it works now with the kernel 5.14.21-150400.24.97. I have the following kernels and related rpm installed (from standard 15.4 repository): 5.14.21-150400.24.88 5.14.21-150400.24.92 5.14.21-150400.24.97 Means for every kernel the package: kernel-default kernel-default-extra kernel-default-optional And I 'juggled' with the kernel-macros package between the versions and used YaST Bootloader module in between changing default kernel. Now it works and I've no idea, what was the reason for this. If it happens again, I'll have a closer look on the constellation. Please let me know, if you need further information. Will put the bug status to RESOLVED - WORKSFORME. Thank's a lot fot your help! Peter -- You are receiving this mail because: You are the assignee for the bug.
