Resolved Date: Aug 15, 2013
Found In Version: 5.0.1
Fix Version: 5.0.1,5.0.1.7
Severity: Severe
Applicable for: Wind River Linux 5
Component/s: BSP - Async
Host OS: Linux Red Hat
Architecture: MIPS
The kdump would failed on the NFS mount when used the NAE.
If using the PCIE e1000e NIC to mount NFS, then it would hung on VFS.
The kexec could test PASS.
It came from the latest RCPL5 LP04 DVD, and it added the CPU_HUTPLUG feature.
The NAE mount NFS failure information as follow:

INIT: version 2.88 booting
Checking SELinux security contexts:
* SELinux requires the root '/' filesystem support extended
filesystem attributes (XATTRs). It does not appear that this
filesystem has extended attribute support or it is not enabled.
- To continue using SELinux you will need to enable extended
attribute support on the root device.
- To disable SELinux, please add "selinux=0" in the kernel
command line.
- This system is using NFS root filesystem, so enforcing mode will
be 22:<5>type=1404 audit(1152666362.940:4): enforcing=0 old_enforcing=1 auid=4294967295 ses=4294967295
disabled for users to continue to use this system.
But, you should *NOT* use NFS root filesystem with SELinux in your
production machines.

Need to add "rootwait" in the command line when using the kdump feature.
1) /folk/lpg-build/cdc/sustaining/WR5015LX04/wrlinux-5/wrlinux/configure --enable-board=bcm-xlp --enable-kernel=cgl --enable-rootfs=glibc_cgl --with-template=feature/kexec,feature/kdump --enable-jobs=8 --enable-parallel-pkgbuilds=6 --enable-internet-download=yes --with-rcpl-version=0005
2) make fs
3) boot the new kernel and FS
4) According to the Kdump testing step from the README.
