Description of problem:
kmod-ixgbe is listed in the "New Packages" section of the 6.2 Technical Notes:

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.2_Technical_Notes/ch03.html 

However, kmod-ixgbe was built for RHEL 6.1 and is not kABI-compatible with RHEL 6.2 kernels. Because of this, an attempt to install this module on a RHEL 6.2 system results in error.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Version-Release number of selected component (if applicable):
kmod-ixgbe-3.4.8_k-3.el6_1

How reproducible:
Always. However, if there is any kernel from RHEL 6.1 on the system, no error occurs because it fulfils the requirement.

Steps to Reproduce:
1. Install RHEL 6.2
2. Install kmod-ixgbe
3.
  
Actual results:
Installation of kmod-ixgbe fails.

Expected results:
Installation of kmod-ixgbe fails.

Additional info:
This may sound awkward but the failure is the expected result in this case. The issue here is that kmod-ixgbe does not belong in RHEL 6.2 and therefore should not be listed in the 6.2 Tech Notes.

By the same (or similar) token, kmod-igb-3.0.6_k-2.el6_1 and kmod-tg3-3.119-2.el6_1 should be removed from the 6.2 Notes. The 6.2 kernels contain all of these as in-kernel modules (same version as those in kmods).
