Description raz 2011-03-30 08:29:56 UTC 
Description of problem:

booting 2.6.38 in redhat 5.3 is not possible due to old ramfs format.
when creating ramfs with mkinitrd, the initramfs image fails to mount / . 

console looks like this:
...
mount: could not find filesystem /dev/root ...
setuproot: error mounting /proc
setuproot: error mounting /sys
switching to new root and running init.
umount old /dev/
umount old /proc
umount old /sys

switchroot:mount failed : No such file or directory ..
panic...



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


How reproducible:


Steps to Reproduce:
1.build 2.6.38 on redhat 5.3 
2. install it 
3.  mkinitrd ...
4. fix grub to boot 2.6.38
5. reboot
  
Actual results:
panic

Expected results:
boot

Additional info:

to bypass this problem I was forced to hack initramfs with initrmafs from fc14 and replace the kernel modules.

We do not support the booting of upstream kernels in RHEL5 (or any RHEL for that matter).
