I am unable to boot the latest snapshot from the following URLs:
ftp://releng.netbsd.org/pub/NetBSD-daily/200209080000/
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.6/

The snapshot from the naobsd site works fine however.

I have a IBM Workpad Z50 with 340 MB Microdrive and it gives the
following errors.  It looks like it is not waiting long enough before
trying to mount the root.  Naoki's kernel outputs "pcmcia1: card irq 3"
four times before trying to mount.  Does anybody else have this problem?
