Update:
There is a new ISO & TGZ, MLNX_OFED_LINUX-2.1-1.0.0-rhel6.5-x86_64
This ISO will install on CentOS and Scientific Linux with the latest kernel update, 431
Although I have discovered the following issues.
Scientific Linux will need the following:
Rebuild the RPMs with mlnx_add_kernel_support
Mount the new ISO or extract the new TGZ
Then use mlnxofedinstall --skip-distro-check in the new rebuilt ISO or TGZ
Both CentOS and Scientific will have the following boot errors:
/etc/rc.d/rc.sysinit: line 149: /etc/rc.modules: Permission denied
