kernel upgrade doesn't work

[Bernd Prager]

Hi,

I'm new to grub. I decided when I'm upgraded to RedHat 7.2 to try 'grub' instead of 'lilo'.

When I try to upgrade my kernel now, I did the usual 'make all', 'make bzImage' and then

copied vmlinuz and System.map to /boot.

 

I changed /boot/grub/grub.conf to:

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.7-10smp)
        root (hd0,0)
        kernel /vmlinuz-2.4.7-10smp ro root=/dev/hda6
        initrd /initrd-2.4.7-10smp.img
title Red Hat Linux-new (2.4.18)
        root (hd0,0)
        kernel /vmlinuz-2.4.18 ro root=/dev/hda6

 

But booting the new kernel fails with:

---- snip -----------

Boot 'Red Hat Linux-new (2.4.18)'

root (hd0,0)

  Filesystem type is ext2fs, partition type 0x83

kernel /vmlinuz-2.4.18 ro root=/dev/hda6

Error 13: Invalid or unsupported executable format

---- snip -----------

 

I was searching the docs and the mailing archive for any hints, but

I couldn't find anything useful.

Do I miss something? What am I doing wrong?

(Fortunately booting the old kernel still works fine.) 

 

Thanks for any help,

-- Bernd
