I'm seeing the same thing, except in my case it is while trying to
install 1.4 onto an old 486-machine (no PCI). I.e. what I see is
wdc0:0:0: device timeout
over and over when booting from the install floppy. First I thought it
must be broken h/w, but since other OSes (not to mention by name)
install nicely it seems like a NetBSD problem.
Please note that since I'm installing stock 1.4 (straight from the
Usenix-CD) it does not appear to be only a recent problem.
