Comment 1 Bill Nottingham 2008-10-01 19:08:13 UTC

If this is validation, is IBM planning to validate this on the RHEL 6 codebase?

If there is code (a target is listed), is it actually in 2.6.27?

Comment 2 IBM Bug Proxy 2009-02-13 20:40:28 UTC

The upstream eHEA driver code has been supporting this feature since 2.6.27. Since RHEL6 will have a base kernel even higher than this level, I'm closing this feature as "fix already available."

Comment 3 Bill Nottingham 2009-02-13 21:49:30 UTC

OK, setting to MODIFIED on this end.

The feature requested has already been accepted into the upstream code base
planned for the next major release of Red Hat Enterprise Linux.

When the next milestone release of Red Hat Enterprise Linux 6 is available,
please verify that the feature requested is present and functioning as
desired.

Comment 4 Kevin W Monroe 2009-11-12 23:18:19 UTC

Closing as support is available in current release.
