Quoting Robert Millan <address@hidden>:
My guess is kernel.elf doesn't include the necessary code. It's about
60k long.
Now I'm sure about that. Unfortunately, grub-mkimage produces images
that the OpenFirmware fails to load with "CLAIM failed" (even with
just one short module). Indeed, bad things started with the first
commit on 2007-02-21. I'm afraid I won't be able to figure it out
without Hollis.
(Not to put any pressure of anyone, but GNU ChangeLog shows its age
here - the detailed changes are described, but the motivation behind
the whole patch is not, yet the details can be recovered with the
version control, whereas the motivation has to be guessed)
Sounds like "DISK-LABEL: read of block0 failed" is printed by the firmware
and not by GRUB.
Also, device enumeration is the same for all devices, so the fact that it
only appears for some of them hints at a firmware bug.
Both ide0/disk and cd refer to the CD-ROM. The messages are not shown
if there is a CD in the drive.
What happens if you set debug=disk ?
Typing from another monitor, sorry for possible typos.
