Putting in NEEDINFO pending upstream code & acceptance.
I have not completed testing on the EEH patch for 48192 and addressing some issues with the patch. I will not make the deadline to mainline.
I will give an update when testing and issues are resolved.
Is this in 2.6.31?
If not, then get the patches upstream, and re-open this BZ providing a backport to RHEL 6 kernel 2.6.31.
