Yes - I removed the compile/FOO directory before building the FOO kernel.

I tried to boot the GENERICADP kernel ftp-ed from NetBSD.org on one of
the machines.  It has exactly the same problem - it tries to change the
root to the non-existent wd0 and panics.  Here is the boot output from
a NetBSD1.2beta kernel booting on exactly the same hardware (modulo a
change of sd0 from a 2GB Quantum to a 730MB IBM drive):

changing root device to sd0a

The generic kernel doesn't recognize the various ed? interfaces properly,
and it thinks the Adaptec host adaptor is ahc1,  but everything else looked
OK until it tried to change root to wd0.
