Hi kernel hackers,
I have a problem with a GPIB PCI card from Quancom ( http://quancom.de/qprod01/eng/pb/pci_gpib.htm ).
I wrote a programm to read data <100kByte/sec from the GPIB bus to the RAM. When the PCI card shares it's IRQ it works for some time and then hardlocks my computer - the "PCI access LED" of the GPIB card is always ON then. Now I found a PCI slot where the card doesn't have to share the IRQ - but linux ignores the card :-( While booting the kernel says: --- <6>PCI: Probing PCI hardware <4>PCI: ACPI tables contain no PCI IRQ routing entries <4>PCI: Probing PCI hardware (bus 00) <3>PCI: device 00:09.0 has unknown header type 04, ignoring. <6>PCI: Using IRQ router VIA [1106/3074] at 00:11.0 ---
The BIOS bootscreen reported an "unknown device - IRQ5". But "lspci" doesn't show up the card!!!
What is "unknown header type 04" ? Why does "lspci" show the card when IRQ is shared? How can I know what's wrong with this card?
Somebody please enlighten me. Please CC me your mail - I'm not subscribed to the list.
Greetings Michael
PS: I already had trouble with this card spontaneously getting unconfigured (like before the BIOS talks to the card) in an ECS L7S7A board ...
My system: Athlon 2000XP 512MB RAM Epox 8KHA+ (VIA KT266a)
Suse8.2 2.4.22 kernel 3.1.97 linux gpib driver
