I think part of the problem is that your report has confused people so that everyone cc'd thinks it's someone else's problem. :-) To wit.. >>> One of our users gets kernel panics from time to time when he tries >>> to >>> use his Amazon EC2 instance with CentOS7 x64 in it [1].

If you can reproduce this with a relatively recent stock kernel, please post the kernel version and the debug information. If you can't, then it's likely to be an issue that RH needs to take care of by backporting whatever change fixed the issue.
