     To put it mildly, it did not work on my SS-10 with Hypersparc.  It is
VERY freaky.  The first time I tried to boot it would hang when it tried to 
add swap.  I hadn't stripped vmlinux yet, so I went and tried that, then it 
got past adding swap but freaked when it should have run the init scripts.

Here is what it looks like:

INIT: iyåpÞªxÜ

     Notice the weird stuff after INIT, this is exactly how it printed, with
those weird characters.

	... skipped a bunch of stuff that the init scripts would normally do,
like mounting the local file systems.

Mounting remote filesystems.mount: RPC: Port mapper failure - RPC: Unable to send
mount: RPC: Port mapper failure - RPC: Unable to send

touch: /var/lock/subsys/nfsfs: No such file or directory

logout

     Notice the logout, odd since I had never "logged in".

     Then immediately went into spin_lock deadlock.

     I booted it several times, this was completely reproducible.  Here is
same run through ksymoops, and I did link System.map to the System.map for
this kernel so should be the correct symbols.  Also, I do not have support for
loadable modules compiled in, so ksymoops isn't going to find info on them.

ksymoops 2.3.3 on sparc 2.2.16.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.2.16/ (default)
     -m /boot/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
