In other words, your kernel is tainted, but all modules are GPL.

See also the check in panic.c:
...
tainted & TAINT_PROPRIETARY_MODULE ? 'P' : 'G',
...

It seems that yout kernel was tainted by a machine check exception (MCE).
This should be visible in dmesg somewhere, and might indicate a hardware
problem.
