A600GS stopped booting

[THX-1138]

(I have not seen this mentioned elsewhere)

After sorting out the other problems by reflashing the internal SD, it's been running well.   I booted it this morning and it took longer than usual and instead of the red pointer, a standard Linux one was showing but the game menu loaded.  I decided to reboot to see if the pointer would go back to normal.  The (plymouth?) loading screen appeared then the screen went black.  I left it a good 10 minutes when I came back to the machine it was still a black screen.  CTRL-ALT-DELETE actually rebooted (usually has no effect) but to a blank screen.  Powered off, left it a few minutes and started again - nothing - just a black screen.   No matter what I do, I'm getting a video output - but it's just a black screen.

OK, I'll see if I can salvage the backups I made from the SD.
Then I will re-flash from the image I was given.

This problem has persisted, I've had a few times where the system would not boot fully.  Each time, I've re-flashed the SD card and setup everything again.

Tonight it has happened once more, no pattern to it.  At power-on the boot screen appears with the progress bar.  The progress goes full speed to 3/4 of the way through, the final 1/4th becomes ever slower, after 5 minutes it completes and says "AMIGA KIT", but progresses no further.
