I am trying to compile a -current kernel (ftp'ed sys.tar.gz from
a few days ago). I have applied the mw-diffs-bla-bla-bla which among other
things contain a patch for the Retina Z3 driver for using a 32bit sprite.

Now, my A4091 won't find my drive at all, the drive is not identified and
the kernel stops with 'no suitable root'. I seem to remember that someone
talked about a similar problem and I would be interrested in knowing what
is wrong. I have looked for the problem myself for a while, but to no avail.
The only thing I really konw is that there is a 'ports' interrupt just after
the afsc device is initialized and that the afsc_dmaintr skips this interrupt
at this place:

                rp = dev->sc_siopp;
                istat = rp->siop_istat;
                if ((istat & (SIOP_ISTAT_SIP | SIOP_ISTAT_DIP)) == 0)

(I suppose that means the siop hasn't sent any interrupt?). Well, I don't
think I have anything else that could have generated this interrupt, and
as I said it was generated just after the afsc device was initialized, so
to me this seems a little strange.

Any help appreciated.

Bye /Andreas
