Manually booting such as with "boot hd:,\\grub" returns a "CLAIM failed"
error. I'd be grateful for any troubleshooting tips.
Has anyone else run into this issue? Should I try rebuilding grub and/or
the kernel myself?
Not yet, but I haven't performed a dist-upgrade on my PowerBook G4 yet which
I am using for these tests. I will try to do that over the next days and
see if I can reproduce this.
An excerpt from the OFW console is attached. I even checked the space
weather because for 3 machines to fail at once like this, it's either
software or a solar flare :-)
I think it would be wise to report this to the grub-devel upstream mailing
list [1] and see if you can get any feedback. The background is that Debian
backports upstream changes from time to time and I could imagine that some
of the recent PowerPC-related changes may have broken your machine.
Do you happen to know what the last working grub-ieee1275 version was?
