Yes - EISA is known to be broken....certain people should have
enough information at this point to write the code but
it's not trivial to get working. EISA just isn't that exciting
these days.

If so, that's probably documented in one of the user guides.
See "Tech Documentation" on www.parisc-linux.org.
Possibly this one:

See the FAQ for how to report kernel bugs - some good
tips there on what's needed.

Can you connect a serial console and capture the entire output?
Normally, one just needs to disconnect the keyboard and
talk to serial port 1 with minicom from another box.

I'm pretty sure this worked before on C200/C240/C360
machines before.
