In a further mail, Joerg reports this suggested fix works for him.

Please, all others that had problems, either

- download the netbsd.grfclfix.v2.{gz,README} from ftp.netbsd.org,
  directory /pub/NetBSD/arch/amiga/misc/

        or

- build your own kernel, with options DIAGNOSTIC included, and the patch
  below,

in both cases, report the results as soon as possible, best until
Monday evening central European time?

        Ignatios
