[Bug 1575394] Re: Yaboot fails to load Ubuntu (MATE & Lubuntu) 16.04 LTS

[Matevz Langus]

Hi,

I have seen the same issue on PowerMac G5 2.5 Quad PowerMac11,2

The problem is in ofpath script. I managed to get around the issue by
replacing ofpath coming with Ubuntu with the fresh one from yaboot
1.3.17 source package + applying the patch (patch provided on links
bellow)

Please have a look at:
https://bugs.launchpad.net/ubuntu/+source/yaboot/+bug/1400030
or
https://lists.ozlabs.org/pipermail/yaboot-devel/2014-December/000483.html

regards,
  Matevz

Title:
  Yaboot fails to load Ubuntu (MATE & Lubuntu) 16.04 LTS

Status in yaboot package in Ubuntu:
  New

Bug description:
  Installations of Ubuntu 16.04 LTS flavours (Ubuntue MATE & Lubuntu)
  succeed on a PowerMac G5 2.0 DP (Mid-2004 - M9455LL/A - PowerMac7,3 -
  A1047 - 1969C), but Yaboot does not load the OS afterwards.

  
  This was tested at first on a multiboot configuration (together with MacOS X Leopard) and later on a single partition (=Linux) configuration to no avail. The target is a Intel 320 SSD resting in the lower bay (B).

  In the latter (more basic) configuration Yaboot starts at least right
  away (no manual load through OpenFirmware needed) but still can't
  properly initiate the Linux boot.

  Error msg:

  Welcome to yaboot version 1.3.16
  Enter "help" to get some basic usage information
  boot: Linux
  Please wait, loading kernel...
  PARTITION is not a number/ht at 0,f2000000/pci at 7/k2-sata-root at c/@ffffffffffffffff/@0:2,/boot/vmlinux: Unknown or corrupt filesystem
