Description Arnd Bergmann 2008-04-28 06:39:25 EDT
Version-Release number of selected component (if applicable):

RHEL5u1 with kernel-debug-2.6.18-91.el5.ppc64.rpm prerelease kernel

How reproducible:

Follow the instructions for NFS root from
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/release-notes/RELEASE-NOTES-U1-ppc-en.html

The machine is a diskless IBM QS21 Cell/B.E. blade server.
  
Actual results:

Boot messages contain:
hub 3-0:1.0: USB hub found
hub 3-0:1.0: 5 ports detected
Loading sunrpc.ko module
Loading nfs.ko module
nfs: Unknown symbol __fscache_relinquish_cookie

nfs: Unknown symbol lockd_up_proto
nfs: Unknown symbol __fscache_read_or_alloc_page

nfs: Unknown symbol __fscache_register_netfs
insmod: error inserting '/lib/nfipr: Unknown symbol ata_sas_port_init
s.ko': -1 Unknowipr: Unknown symbol scsi_device_get
n symbol in moduipr: Unknown symbol scsi_block_requests

Expected results:

regular boot from NFS, as with RHEL5u1 kernel.

Additional info:

This was reported to me by a blade customer, "Howard D. Gray"

To get it all working I altered mkinitrd like this:

My script to build the initrd and combine with the kernel image looks
like this:
