powerpc ibm pseries 620 stopping after kernel load

Looks like a ppc64 issue. Can someone from the kernel team take a look at this?

Thanks!

Hi Ulrich,

Care to actually test the latest Hardy Alpha release. It has an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/ports/daily/current/ . If you can, please verify if this bug still exists or not and report back your results. Thanks

Hi Leann

I will try it today and report back.

All the best
Ulrich

Hi Leann

I tried the install on the IBM pseries 620, but it did not work. Please
see below the text from the kernel load process, started with three
difirent options:

Hi Ulrich,

How is your console connected on this machine? Are you using a management center console or a serial cable?

Also, try adding 'debug' to the kernel command line, to override the default 'quiet' option. Let us know what output you get with that.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Have you tried booting the latest Jaunty alternate PowerPC CD? If you could try that for me, and let me know if it works, that would be appreciated.

Thanks.

Hi Luke

I am happy to try it for you.

Do you know if there is a South African server that is hosting the PPC
cd images. All the servers I looked at only hosts the i386 images.

In South African local bandwidth is cheaper than international bandwidth.

All the best
Ulrich

Sorry, I only know if http://cdimage.ubuntu.com/ports/releases.

Let me know how it goes.

Hi Luke

I tried install via latest Jaunty alternate PowerPC CD. It did not
work, see the output below. I tried Debian 5, which should be using
the same installer if I am not mistaken, and that installed
successfully.

Output:

Ubuntu PPC

To boot any other label simply type its name and press <return>.

To boot a kernel image which is not defined in the yaboot configuration
file, enter the kernel image name as [[device:][partno],]/path, where
"device:" is the OpenFirmware device path to the disk the image
resides on, and "partno" is the partition number the image resides on.
Note that the comma (,) is only required if you specify an OpenFirmware
device, if you only specify a filename you should not start it with a ","

If you omit "device:" and "partno" yaboot will use the values of
"device=" and "partition=" in yaboot.conf, right now those are set to:
device=/pci@fff7f09000/pci@b/scsi@1/sd@1,0
partition=0
