Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Qixiang, Can you confirm that this bug is supposed to be against RHEL 6? I just hit this in RHEL 5 and have a fix for that. It's caused by the loop module not being loaded. It seems loop is compiled in to the Fedora kernel, so we never hit this. I'd expect it to be compiled in on RHEL 6 too.
