[Bug 56885] Re: e1000 driver not working properly on x86_64?

[Herbert V. Riedel]

mystery solved:

MSI-PCI Interrupts weren't triggered... (/proc/interrupts showed always
zero interrupts), and the frame statistics are updated through a kernel-
timer-invoked update-function by reading NIC internal registers holding
the required statistics data...

by compililing the driver with "make CFLAGS_EXTRA=-DDISABLE_PCI_MSI" and
therefore falling back to 'IO-APIC' interrupts, frames started to show
up in the network stack :-)

so now it seems to me, that it's just a matter of incomplete/broken MSI
support with the involved chipsets...  :-/
