Bug Description

on a freshly installed dapper/x86_64 install, the e1000 supported intel Intel Pro/1000 PT
Server NIC was detected and configured, link gets detected, but it doesn't seem to receive ethernet frames (although the RX packet counters do increase, but no rx frame shows up in tcpdump)

alas it's a remote system which I don't have physical access to right now, so I can't easily try out a 32bit kernel, in order to verify my suspicion that it's simply a 64bit-bug kernel driver bug...

I've tried with intel's 7.2.7 e1000 version, but still no luck:

packets exit the ethernet adapter on the wire, and also show up in tcpdump, but no ethernet frame seems to get received from the wire (although still getting increased frame-rx counters...)

Herbert V. Riedel (hvr) wrote :

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... :-/

Ben Collins (ben-collins) wrote :

This change will show up soon in dapper-proposed.

I didn't remove the capability for MSI to work, but it's disabled by default now. Re-enable by doing enable_msi=1 when loading the module (for anyone that knows it works, or wants to find out).

I am having a similar problem with the Intel Pro 1000 PT desktop card. Here is the output of lspci:

0000:05:00.0 Ethernet controller: Intel Corporation: Unknown device 10b9 (rev 06)

This is after updating my kernel to the one from dapper-proposed. So the kernel update didn't fix my problem.

Kevin Harriss (kharriss-id) wrote :

I booted off of a Feisty cd (7.04) and the network card worked fine. So this problem is only with Dapper.

Kevin Harriss (kharriss-id) wrote :

I was wondering if there were any updates to this bug or if there is any more info I can provide to help fix this bug.

Martin Pitt (pitti) wrote :

Kevin, indeed you could help us by installing the kernel from dapper-proposed (just enable dapper-proposed and do a dist-upgrade) and tell us whether the e1000 card works then. Thank you!

Kevin Harriss (kharriss-id) wrote :

Martin, that is what I did and the card didn't work. I am not running dapper on this box any more as I needed to get the box up and running. It is currently running Gutsy and the e1000 card is working fine in Gusty.

I downloaded the dapper daily build from 20071207.2 and booted from the CD. I was able to successfully get an IP address and wget a web page with the following network adapter on amd64:

Fixed kernel is in dapper-updates now.

I'm having the exact problem described above in 8.04 x64. Not finding much info out there. Any ideas? Any info I can post to help?
