From NW_Pilot's adventu
Apparently the added pressure in the fuel
tanks pushed the floats in the fuel tank
up, which got the Garmin confused, causing
an error that made it reboot.

Steam gauges don't get confused like that. While they do sometimes go
bad or give an incorrect indication, the fault is isolated to that one
gauge; it doesn't cause the entire airplane to have an apoplectic fit.
That is left to the pilot. One of the real dangers of glass is that it
usurps the pilot's perogative to panic (or not) by doing so itself.

If there's ever an argument against glass (or "advanced integrated
flight instrumentations and controls"), this is it!

Day 5: Shut down in Iceland with 55 knot headwinds. I make the call "No Go"!!!

NW-Pilot, would you have gone with 55 knot tailwinds?

ibid: (spelling note, day 11)
After everything else that has happened, this makes me not want to every own a newer model Cessna, or anything with a G1000.

....not want to ever own...
(public service, not nitpicking)

(same day)
Everything else was uneventful, as I went direct KAD and had a small dialogue with the tower about my permission to land.

Anything interesting in that "dialog"?

Anyway, that's quite an adventure! Would you do it again?
