Hi,

if I remember correctly the result of the issue showed up in 2 places

1) there is a script called ofboot.b which is a script for Open Firmware. Bootloader that loads before yaboot.
The problem was already in this script. So what I initially did was booting rescue cd and mounting /dev/sda2 (this is where boot partition with yaboot is) and modifying ofboot.b
Then I got yaboot and then tried to find the right path in yaboot.

At the end it turned out to be wrongly generated openfirmware path. Perhaps I should create a fix for ofpath script coming with yaboot 1.3.16 which comes as default with Ubuntu.
I just hoped 1.3.17 would resolve the issue by itself but it did not. So I stayed with 1.3.17 for my machine.

regards,
  Matevz
