If I build using latest git add just add infiniband I am able to use infiniband uverbs without any issues. If I turn on XEN with dom0 in the config and run that kernel infiniband uverbs does not pass data, ibv_rc_pingpong just sits there.

Any ideas? Anyone get infiniband and xen working in a kernel? I talked to the QFED guys and they say that since infiniband works in the kernel just fine that I have to talk to the xen guys. :(

Interesting, the same kernel works if I load it without xen.

Working Infiniband:
title Fedora (
        root (hd0,0)
        kernel /boot/vmlinuz- ro 
root=UUID=b770a383-39e0-48c5-91f5-6c0630f42410 rhgb quiet
        initrd /boot/initrd-

Broken Infiniband:
title Fedora (
        root (hd0,0)
        kernel /boot/xen-3.4.1.gz
        module /boot/vmlinuz- ro 
root=UUID=b770a383-39e0-48c5-91f5-6c0630f42410 rhgb quiet
