Pinned topic Debian on Power 740: yaboot can't open device

‏2011-09-07T08:15:09Z |
Hello everybody!

I'm in the process of installing Debian Stable on a Power 740 system.
I'm familiar with the installation on x86 systems and the installation process of Debian ppc thus looked familiar.

I installed using the "install64" option. Disk partition was "guided - use whole disk, with separate /home". Installation concluded successfully but after a reboot yaboot loads and offers the choice of "Linux" and "old" - as per standard configuration I learned - but booting "Linux" fails:

Config file read, 4096 bytes Welcome to yaboot version 1.3.13 Enter 
"help" to get some basic usage information boot: Linux                      old boot: Please wait, loading kernel... Can
't open device </vdevice/v-scsi@30000002/@1:0>                                /vdevice/v-scsi@30000002/@1:2,/boot/vmlinux: Unable to open file, Invalid device boot:

The device however is valid - I can see it in the SMS menu - and I can successfully boot into the rescue system via the Debian cd ("rescue64") and subsequently chroot into my installed system, no problem.
However, I can never boot straight into it with yaboot.

Some information about the system:

root@debian:/# cat /proc/partitions major minor  #blocks  name 8        0    6291456 sda 8        1       7168 sda1 8        2    1902592 sda2 8        3          1 sda3 8        5     262144 sda5 8        6    4115456 sda6     root@debian:/# cat /etc/yaboot.conf ## yaboot.conf generated by debian-installer ## ## run:

I'm at a loss as to what the problem might be. The installation looks fine within the chroot environment, I just can't get it to boot. Any suggestions would be much appreciated.

    The IBM Power Linux Team is migrating to a new developerWorks Community - Think Power Linux. If you'd be so kind as to join us in that community and repost your question to the Message Board, it will help us encourage others to Think Power Linux!

    Additionally, you might want to check out a new wiki that a developerWorks member created about putting Debian on POWER7 systems - Debian 6 on Power7 LPAR.
