I'm running a e1000xf adapter in a 64-bit/100Mhz PCI slot. The intel site shows this is a supported config for the card, but linux is pulling this info:
ed:02.0 Ethernet controller: Intel Corporation 82544EI Gigabit Ethernet Controller (Fiber) (rev 02) Subsystem: Intel Corporation PRO/1000 XF Server Adapter Flags: bus master, 66Mhz, medium devsel, latency 64, IRQ 18 Memory at f7fe0000 (64-bit, non-prefetchable) [size=128K] Memory at f7fc0000 (64-bit, non-prefetchable) [size=128K] I/O ports at 7000 [size=32] [virtual] Expansion ROM at f10a0000 [disabled] [size=128K] Capabilities: [dc] Power Management version 2 Capabilities: [e4] PCI-X non-bridge device Capabilities: [f0] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-
My thoughput tests show it is definitely not running at the 100Mhz bus rate is should be capable of. Any ideas on how to make it work at full speed? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
