Well, the bug was reported against RHEL 6.7 which has not been released yet.
Fresh steaming proof as requested:
https://bugzilla.redhat.com/buglist.cgi?bug_severity=urgent&...
All high severity bugs against 7.1 which was relased 16 days ago. Check the dates on half of them. They're before the release date and half of them haven't even been assigned or triaged.
When 7.0 came out, datetimectl and systemd didn't even work properly. Enabling ntp threw dbus errors galore. On some kit it didn't even boot. Total lemon.
RHEL doesn't generally work properly until the .2 releases. I've been using it for 10 years so I've got plenty of experience on the matter.
I would go into detail about the CIFS/smb kernel hangs I've had on 6.x but I've had enough of it by now.
Update: I think if you wanted to find out which critical bugs affected RHEL 7.0 on release, you'd probably want to look at the list of z-stream packages (RHEL 7.0.z) which subscribers have access to. These are bugs which didn't affect the installer or first boot, but were important enough to need fixing in RHEL 7.0 after it went out. (If a bug was critical enough to affect installation or first boot, it would have delayed the release).

Couple that with what rwmj said, you've effectively debunked yourself.
