Yes, there should be debug output.  When the UNDI EBUSY patch refuses
to load multiple UNDIs the following debug message is printed:
UNDI 0xXXXXXXXX cannot load multiple instances

I looked at the patch again and spotted a trivial mistake: it was
refusing to load the first UNDI rather than all UNDIs after that (the
logic was inverted).  The patch in git is updated to correct my
mistake.

Sorry for that hickup, this new patch should allow the first UNDI
device to load.

You can grab the latest change by cloning again:
git clone git://git.etherboot.org/scm/people/stefanha/gpxe.git
cd gpxe && git checkout origin/stefanha-50-undiebusy

(The changes can be pulled into an existing repo, but the commands
depend on how the repo has been set up.  That's why I give these
commands which are guaranteed to work but clone a new repo.)

You can try enabling PCI debug messages (that includes probing devices
and you should definitely get output):
make DEBUG=undiload,undi,undinet,undirom,pci

If you see no PCI debug messages then config options need to be
checked (any customizations in config/* like CONSOLE_SERIAL?).

Thanks again for testing this,
Stefan
