My next guess is an unaligned access not using {get,put}_unaligned(), which
doesn't seem to work on tx4927, but doesn't cause an exception neither.

IIRC, TX49 can raise an exception on unaligned access.

I thought so, too, but had verified that reading from an unaligned address
didn't raise an exception, but returned a corrupt value instead.

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
