Can you attach any logs that are present after the machine reboots? Without knowing where it's rebooting at we're going to have a difficult time doing anything about this bug.

kernel 3.13.7-200.fc20.x86_64 exhibit the same result 1) Re-installed linux from DVD: Kernel 3.11.10-301.fc20.x86_64 2) Run yum update, which at this time, installs 3.13.7-200.fc20.x86_64 3) Run init 6 The machines then keeps rebooting when loading new kernel. How can one trace what module is causing this?
You might try passing 'initcall_debug' on the kernel command line.

Kernel 3.14.4-200.fc20.x86_64 did not resolve the issue. Still on the original kernel 3.11.10-301.fc20.x86_64 to avoid reboots.
Kernel 3.15.4-200 mentions in it's boot procedure log twice that it is failing to load the kernel modules... then hangs or attempts reboot. Issue persists.
