[Letux-kernel] Oops while booting 5.15.2 on Nokia N900

Hi Sebastian,
I have found an old N900 and thought about trying to boot it. It shows "Nokia" on the screen,
the vibra does a short rumble and then screen goes black (backlight remains enabled).
And after some seconds the sequence repeats.

The above page links to http://wiki.maemo.org/N900_Hardware_Hacking#Debug_ports where
the test pads under the battery are described.

But I can't match the picture (the one with o and + in the box) with my board.

There, the 6 pin connector has a regular pattern (o o o   o o o o in two rows shifted against each other).

Any idea how to correctly interpret the wiki entry? Are there missing some spaces before "J2062"?

BR and thanks,
