That link provided interesting reading, but I'm not buying the word
"brick" in the sense that I normally reserve it for (e.g., ARM-based
devices that you now need to hook up to debugging hardware to revive) --
if so, it would mean that your hard disk dying would render your entire
system dead. Pretty sure the author goofed on that particular choice of
word. Though I suppose that if you keep secure EFI enabled, a dead disk
might make that seem like the case, in which case you'd have to play
games in the firmware of your system.

I didn't get that from the article, either. Writing to NVM -- or BIOS
-- is something you want to do some times, sure, but I'm hard-pressed to
think of a situation where that would actually prevent a boot, instead
of simply throwing an error or two. Thus my original suggestion that
the OP disable splash and quiet in the kernel boot line in order to
root-cause the issue at-hand.
