After installing the new 5.15.0-79 kernel image, my ThinkPad L490 fails to start.
A normal boot just gives me a blank scree, when I boot in recovery mode it hangs at: "EFI stub: UEFI Secure boot is enabled". Editing the kernel entry in grub as suggested here https://wiki.ubuntu.com/DebuggingKernelBoot does not yield any more info.
Starting with 5.15.0-78 works without issues.
