Description Trevor Davenport 2006-04-07 18:54:16 EDT
On a PowerMac3 G4 500 mhz with a seagate 17gb scsi hard drive, after installing
the booting hangs once the loading second stage bootstrap appears. 

running nvsetenv boot-device prints:
# nvsetenv boot-device

running ybin -v prints:
ybin: Installing first stage bootstrap /usr/lib/yaboot/ofboot onto /dev/sda2...
ybin: Installing primary bootstrap /usr/lib/yaboot/yaboot onto /dev/sda2...
ybin: Installing /etc/yaboot.conf onto /dev/sda2...
ybin: Setting attributes on ofboot...
ybin: Setting attributes on yaboot...
ybin: Setting attributes on yaboot.conf...
ybin: Blessing /dev/sda2 with Holy Penguin Pee...
ybin: Updating OpenFirmware boot-device variable in nvram...

In OpenFirmware running devalias prints the hd alias as:
hd    /pci@f2000000/@d/mac-io@7/ata/4@1f000/disk@0

Comment 2 Trevor Davenport 2006-04-07 19:04:32 EDT
The ofboot option in the config file was only added in an effort to fix the
problem but it had no effect.  I also tried hd:2 but both just stop at the
loading second stage bootstrap..... prompt and then eventually bring up the
purple mac icon withe the question mark.

ofboot.b from /dev/sda2
Comment 4 Trevor Davenport 2006-04-08 15:34:41 EDT
After much experimenting I think I know what is happening though I'm still not
sure what to do to fix it.  I found this through using and ubuntu live cd and
running ybin from it would always make the system bootable so I used the ofpath
command from the live to show the OF path to the boot partition which gave me:


but inside of fedora then ofpath returns 


it is missing the ,1 after the @4.  manually going into OF and typing:

 boot /pci@f2000000/pci-bridge@d/ATTO,ExpressPCIProUL2D@4,1/@0:2,\\:yaboot 

does indeed start yaboot just fine and the system boots normally but if I type:

boot /pci@f2000000/pci-bridge@d/ATTO,ExpressPCIProUL2D@4,1/@0:2,\\:tbxi 

it goes to the first stage bootstrap as expected but then gets an error loading
yaboot that says it can't open


which is exactly the same as above except there is no : before yaboot.  What I
think is happening is that running ybin in fedora sets the boot-device
incorrectly because for some reason it is getting a path that doesn't work and
then it also can't find yaboot after the first stage because that path is wrong.
 So the system will work after i've run ybin from the live cd ( it doesn't work
if I use rescue mode from the fedora cd) until the next kernel install and it
will break again.
Comment 5 Paul Nasrat 2006-04-08 16:44:07 EDT
Sounds like ofpath is buggy on your setup.  Please provide a tarball of
/proc/device-tree.  What version of yaboot does ubuntu ship with? Can you also
attach the ofpath from ubuntu.
Comment 6 Paul Nasrat 2006-04-08 16:50:04 EDT
Actually I have the ubuntu patches, what does /proc/modules on your machine
contain (I still want /proc/device-tree)

Comment 9 Ian Romanick 2006-05-05 18:52:12 EDT
I see similar behavior on a 1.6GHz G5 PowerMac.  Could this be related to a
particular firmware revision?  I guess that wouldn't explain why the problem
isn't seen on Ubutnu. :(
Comment 10 Paul Nasrat 2006-05-10 14:10:48 EDT
Ian - can you attach /proc/device-tree for your system too.  It's ofpath bug but
a different one for your system.

Comment 12 Paul Nasrat 2006-05-10 21:50:45 EDT
Can you also see what


gives as output for

ofpath /dev/sda
ofpath /dev/sdb

I'm hoping the merge I made from ubuntu's patchset upstream should fix this.

Output of new ofpath

Both /sbin/ofpath and your updated ofpath report "/disk@0:" for /dev/sda, and I
don't have a /dev/sdb. :)  I've attached the output of 'ofpath --debug
/dev/sda' just in case there's useful information there.
Comment 14 Trevor Davenport 2006-07-25 12:56:38 EDT
ofpath /dev/sda

Comment 15 Trevor Davenport 2006-07-25 13:14:29 EDT
with the patched ofpath the boot device is getting set to:


and continues to have a booting problems.  After running ybin from the ubuntu
live cd it gets set to. 


hope this helps.

P.S.  Sorry for such a long time between replying to the bug mail...seems i
didn't get any bug mail about it for some reason and didn't know there was
anything else happening until I decided to check today...cheers
