Maki has been building me kernels until recently.  I setup a cross-compile
toolchain on my Sun3/80 netbsd box, so I can build kernels now.  We seem to
have the L2 cache properly initializing now, but the machine locks solid right
after probing the com ports, and before the root device is probed.
Sticking printf's before and after the call to _splnone() in cpu_configure()
of autoconf.c shows that it is being reached, but is locking solid after
enabling interrupts.  The printf "after" is never reached (see attached output).
Some driver's interrupt code is going south, we think.  Personally, I don't
think it's the scsi asc driver because we have the same problem with kernels
built without the asc driver.
But the problem definitely seems interrupt related, as everything is fine up
to the point _splnone() is called.

Comments?  Suggestions?

Cheers,
-Mark
