2.6.23: GRUB reports "Setup signature not found"

[Chuck Ebbert]

Multiple people have now reported this error message with 2.6.23.
Updating GRUB fixes it:

Thanks for the info.
A better fix IMHO would be if one could get lilo to work.  :)

There is a fix in 2.6.24 series (norminated for 2.6.23.2) that makes it 
work with old versions of LILO -- and unfortunately breaks old 
syslinux... Either way, current versions of LILO should work just fine.

BTW, I definitely can agree with your feeling about grub (which is part 
of why I maintain a different boot loader suite.)  However, if you know 
of any LILO problems, please speak up.

I don't know of any lilo-specific problems and didn't mean to imply
that LILO is at fault.

The problems that I have seen when I have tried to switch from
grub to LILO are more like config issues:
either "can't find root device" or
"cannot open /dev/console" or other initrd/initramfs issues.

Thanks,

OK.  I'd be interested in your experience if you'd be willing to try out 
syslinux (extlinux).

This is indeed a known problem with very old versions of grub.  It would 
appear that Red Hat's rpms for grub don't actually update (some parts 
of?) grub, so it leaves an ancient grub on the system and in use.
