Xserve G5 OpenFirmware 'CLAIM failed' after dist-upgrade

Kia ora from New Zealand!

I run a couple of old Xserve G5s (RackMac3,1) and they have all failed 
to reboot following an "apt-get dist-upgrade", which I normally do every 
month. Installing grub-ieee1275 (2.12-7) seems to have been what did it, 
or maybe it was the kernel, I don't know. The machines drop to the OFW 
console with an "invalid memory access error" instead of booting.

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?

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 :-)

Thanks in advance
