kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo controller cards. this implementation doesn't work for nm9855 based cards! there are two reasons: a) the module 'parport_pc' doesn't want to give the resonsibility for the netmos_9855 to 'parport_serial' and can not handle the serial lines -- trivial to fix... http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in 'parport_serial' still doesn't work because of wrong assumptions about the relevant BARs port address layout for this chip: 0000:00:09.0 Communication controller: NetMos Technology PCI 9855 Multi-I/O Controller (rev 01) (= 9710:9855) Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014) Flags: medium devsel, IRQ 177 I/O ports at a800 [size=8] (= parport) I/O ports at a400 [size=8] I/O ports at a000 [size=8] (= serial) I/O ports at 9800 [size=8] (= serial) I/O ports at 9400 [size=8] (= serial) I/O ports at 9000 [size=16] (= serial) the following patch will fix the problem.
