This bug is probably fixed in 4.0.5-rc2. Can you please test if it fixes this issue for you?

WDOG.FT (fault type) = 3, which is a hardfault. Noting that the watchdog was added specifically due to the MiniPix, I wouldn't be at all surprised if this is a legitimate board hardware error.

I'm on the way .... DEVEL 4.0.5 firmware flashed to several boards; watchdog disabled to be sure about hangs .... up to now, 10h continous running (not flying) with no hungs ... let's wait 20 or 30 more hours ....
