Apparently that's a quirk to fixup bad information that exists
on some machine that identifies itself as "ProLiant MicroServer".

From the panic you can see that the pipmi->smipmi_base_address value
is 0, so that subsequent code tries to map address -7..-6. A quick
fix, is probably to test the base address for a value larger than 7.

Maybe someone with a Microserver N36L that does require the quirk
can tell, what the expected base address is.

Can you try this patch?
