No boot... At all

Hi all
I hope some of you will know what is going on here.

A website triggering WebGL caused a kernel panic, after which these lines shown in picture appear. Unfortunately I now have no boot. Verbose mode and Sudo mode are the only things working. Even recovery is dead, it will attempt to boot, completing half of the progress bar before turning to a grey screen for a while until it shuts down.

Perhaps these error messages will mean something to someone.

I have had this happen to a few computers at our work. Taking it to the Genius bar resulted in a logic board replacement for GPU related issues every time.

That's what I'm getting at too...
Connecting a second monitor, and thus forcing it to use the discrete graphics, clears the lines on screen, but still no boot.

Even booting from usb, windows or os x, it is all the same, loads some, then flashes to grey screen and fires up fans...

Still seems like a logic board error that it is hanging on the boot of the airport card. We again had this issue and a logic board replacement was needed to fix it. You by any chance didn't install custom wifi/bt kernel kext to enable handoff and continuity on an older mac? We had this issue and ran fsck to get it to boot and then removed those it booted back up fine. Did you try holding shift to boot safe mode?

/sbin/fsck-fy returns the picture below.
Safe mode is a no-show. Same as the others, grey screen then fans.

Sudo mode, and verbose mode are the only things that "work" at this stage.

And no, no mods to enable handoff, though that would have been nice....

I love the high speed image capturing on iPhone :)

This is displayed on the very first second of verbose mode.

Also /sbin/fsck -fy resolves nothing, although it did make modifications

That is why I wanted to know what model, but yes it is under apples replacement plan due to that well know issue.
