fixed in sles11sp3 as well in the most recent upstream kernel update from SuSE to version 3.0.101-0.35

[Jodi Levi (Inactive)]

Patches have landed.

Thanks, Bob - It doesn't seem to be, but Cray has support contracts with SUSE, so someone around here should be able to get me in.

Much appreciated.

[Bob Glossman (Inactive)]

btw, the fix isn't in the latest update to 3.0.101-0.29. I expect it in the next one.

Patrick,
It's https://bugzilla.novell.com/show_bug.cgi?id=878123. Don't know if that's generally accessible.

Bob: Are you able to provide a link or other info about that bug report?

Thanks
