patches/packages/linux-5.15.161/*: Upgraded. These updates fix regressions with the 5.15.160 packages. Hopefully we do not get any new ones. :-) Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.
