Hello, this is yet another try to get someone to look at this ;) I can't get PCI-devices to work on my DH77KC mainboard. I tested this using an AVM B1 ISDN card, a Fritz!PCI card and an old 3Com 905c NIC. I attached some dumps in case it helps. The CPU is a Core i7 3770. PCI hardware is detected by the kernel, but it gives IRQ errors. Using irqpoll allows the PCI card to somewhat work, but it is unreliable. There are some reports in Intel's support forums that also report PCI-problems with this mainboard, but Intel doesn't seem to be interested. So I hope this is something that is fixable on the kernel side. If there is more information needed, please let me know. -- Gruß Malte Schröder --------------------------------------------------------------------- MalteSch@gmx.de
