Hmmm... looks like a stray interrupt from the WD controller. You might try
turning that assert into:

        while (inportb(WD_PORT+WD_STATUS) & WDS_BUSY)
                ;

and see if that helps your system. More efficient might be:

        if (...)
            return;

which assumes that another interrupt will arrive for the true completion of
the I/O.

I have a 386sx laptop too, and yes, they aren't very fast by today's
standards!

We've also seen the occasional machine which can't do automatic head select.
You might try removing the "#define AUTO_HEAD" from wd.h before you play
around with the interrupt handling. It generally won't fail with your
symptoms, but you never know.
