From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Dazed and confused, but trying to continue
This is the most confusing and awesome message I've ever had.
What causes that?
An unexpected T_PAAMAYIM_NEKUDOTAYIM.
In all seriousness the relevant bit of code is here:

Seems to be related to NMI SERR handling.
