Summary: Linux chroot uname -r not returning rootimg level

Initial Comment:
On Rh6.2 we were running the procedure to add Melanox OFED to our diskless image. The EMS was running
kernel version 2.6.32-220.el6.x86_64 and the image had been updated to 2.7.1-2.6.32_220.13.1 and the
mellanox support was added for this version.
There are several ofed rpms that are kernel version dependent, for example:
./RPMS/kernel-mft-2.7.1-2.6.32_220.13.1.el6.x86_64.x86_64.rpm
./RPMS/kernel-mft-2.7.1-2.6.32_220.el6.x86_64.x86_64.rpm
The mlnxofedinstall script uses "uname -r" to determine which version of the rpms to install. uname -r returned the EMS level and not the rootimg level. 
dmesg shows the messages:
mlx4_ib: disagrees about version of symbol mlx4_find_cached_vlan
mlx4_ib: Unknown symbol mlx4_find_cached_vlan
mlx4_ib: disagrees about version of symbol mlx4_buf_write_mtt
mlx4_ib: Unknown symbol mlx4_buf_write_mtt
mlx4_ib: Unknown symbol mlx4_cq_ignore_overrun
*
Workaround:
If needed, add the kernel support for ofed and follow the setup instructions to install the ofed rpms. Change the mlnxofedinstall script line:
my $kernel = `uname -r`;
to assign the kernel level:
my $kernel = "2.7.1-2.6.32_220.13.1"

Jie Hua,      Can you look at this xCAT bug  that was opened for Melanox 
IB implementation  with RH6.2  Linux .  
Mark I changed the Group to xCAT 2.7.4   since we made xCAT 2.7.3  GA last
week.  If you need an Efix  we can work with Jie Hua .
