Description Jiri Kastner 2010-10-22 08:01:15 EDT
Description of problem:
rhel6 -> rhel5 provisioning not working, because old yaboot doesn't recognize rhel6 kernel image as valid elf image.

Version-Release number of selected component (if applicable):

How reproducible:
always on rhel5 ppc

Steps to Reproduce:
1. prepare rhel5 ppc machine and satellite-5.4 for provisioning ppc rhel6
2. update it
3. register rhel5 ppc to satellite
4. create kickstart
5. launch this kickstart
6. connect to ppc client console
7. rhel6 kickstart fails
8. boot to linux (boot: linux)
9. download rhel6 yaboot package and extract it and replace files from old yaboot
10. run 'ybin' and reboot again and let machine boot kickstart
11. kernel image is loaded and kickstart launched
Actual results:
Welcome to yaboot version 1.3.13 (Red Hat 1.3.13-10.el5)
Enter "help" to get some basic usage information
boot: kick1287747852
Please wait, loading kernel...
/vmlinuz: Not a valid ELF image

Expected results:
boot: kick1287747852 
Please wait, loading kernel...
   Elf64 kernel loaded...
Loading ramdisk...
ramdisk loaded at 03600000, size: 30590 Kbytes

Could you please tell us if booting RHEL6 kernel from RHEL5 yaboot should be supported?

Comment 7 RHEL Product and Program Management 2010-10-26 08:07:07 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
Comment 10 Roman Rakus 2010-10-29 08:20:25 EDT
