Same problem here with Lilo 22.6.1 and 22.7.3 The problems first appeared after upgrading to the newest initramfs-tools. The upgrade didn't work I had to uninstall all old kernel images and reinstall the running kernel image. The problem was probably caused earlier but I didn't use Lilo until the initramfs-tools.
The systems have Debian etch installed because stable doesn't support my hardware. I have used the Etch installer to make LVM2 in a mdraid setup. Are there any workarounds? I've got 6 servers running etch in lvm2+mdraid. Some of them are in production state now.....
