This is more of a kernel issue than a Gentoo one, but I wonder if anyone has had similar experiences they can share?
My C360 accepts at least one ordinary 32bit/33Mhz/5V PCI card, and judging by the alternate keying in some of the 64bit slots they would also accept what I would term mainstream boards as well, e.g. older PCI graphics cards, Ethernet etc.
I tried a USB2/FireWire board today to see if I could add some modern connectivity to the old girl, and seeing as Linux now thoroughly supports such peripherals and controllers it should expand the usefulness of this box considerably.
Board uses VIA6214 for USB2 and VIA6306 for 1394 - even the PDC firmware (INformation menu -> IO) knows that the board has USB and FW on it.
Kernel drivers (uhci_hcd, ehci_hcd and ohci1394) all get pulled in by udev and pick up/register their respective buses.
BUT when I try to connect a USB device at least, I get a message about a stuck interrupt from the Dino chip bridging the PCI bus and everything slows up until I rmmod the offending HCD module.

Any ideas welcome. Seems the root hubs enumerate alright but connecting an external device does not; bus power is applied but then the stuff about stuck interrupts appears.
Probably need to try enabling some debug output in the HCDs to get meaningful dmesg output. |
