Currently we don't get Fuse and A-MQ on pSeries chipset with RHEL. While we do test pSeries and AIX combination, see the supported configurations page, [1]. We'd like to be able to offer RHEL as an option for customer using IBM pSeries hardware as well.
We have one open issue about the native wrapper for JBoss Fuse with this combination, which is not working with pSeries and RHEL. The same customer is also having using LevelDB corruption using NFSv4, which could be related to the chipSet/OS combination, which would be difficult to test without support from QA.
