Bug#375505: yaboot-installer: generated yaboot.conf is broken on IBM POWER hardware ...
Version: generated yaboot.conf is broken on IBM POWER hardware ...
When installing on IBM JS21 blades, as well as on the augsbourg quad-power5
machines and p505 boxes, the install failed on yaboot-installer.
After investigation, three issues appeared :
1) There was a device= line, with nothing behind it, which yaboot failed to
parse at boot time, and thus rejected the config file or entries. The device =
line is not really necessary, since yaboot is able to recognize the device
from the OF chosen nodes. Removing this line by hand worked just fine.
2) the magicboot=/usr/lib/yaboot/ofboot, and this is the one which caused
yaboot-installer to fail. ybin doesn't support a magicboot line with a raw
install, that is in a PReP boot partition, as is used on IBM POWER. Removing
this line by hand eliminated that problem.
3) These machines use a virtual serial console, namely /dev/hvc* (hvc0 on the
blade center, but hvc1 on the augsbourg virtual partition). yaboot-installer
needs to add the correct console=hvc* into the append line, in order to get a
console after the reboot.
