There is no archive of the old packages for Kernel:HEAD, unfortunately. But now we've already moved to 5.16 final, let's check that again. First off, please confirm that the problem happens with the current kernel in OBS Kernel:stable repo, kernel-default-5.16.0-1.1.g487d6b3.x86_64.rpm. (Note that it's no Kernel:HEAD any longer.) Once after confirming it's broken, install the corresponding kernel-vanilla package, kernel-vanilla-5.16.0-1.1.g487d6b3.x86_64.rpm, boot with this kernel (choose in GRUB menu), and check whether the problem is seen with this kernel or not.
