Most recent kernel where this bug did not occur: 2.6.8 Distribution: Debian Hardware Environment: Dual-PIII, Ethernet Pro 100 and Realtek 8139 PCI interfaces Software Environment: Debian Etch (Testing) Problem Description: The network is not reachable, though the kernel does seem to sense line presence on both interfaces. On boot, udev/discover loads e100, 8139cp and 8139too. /etc/modules does not have any network modules (needs eepro100 for 2.6.8, but I removed it, no change). The relevant lspci listings are: 00:09.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 05) 00:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10) Both interfaces work fine under 2.6.8 as long as eepro100 is loaded. More information (lspci -v, /proc/interrupts, /proc/ioports) can be found at the Debian bug: http://bugs.debian.org/386972 Steps to reproduce: Boot, try to use network.

I'd be assuming that you're not getting any interrupts through for those NICs. Could you please check /proc/interrupts, see if the interrupt counts related to the NICs can be made to increase? Also, the full `dmesg -s 1000000' output might help. We might also get some interesting info if you can compile your own kernel, build thsoe net drivers into vmlinux, capture the dmesg output. If it _is_ an IRQ problem then you might find that fiddling with ACPI helps: disable it in config or boot with `acpi=off', see if that helps. Also try booting with the `pci=routeirq' option. There are various options described under acpi= and pci= in Documentation/kernel-parameters.txt which it would be useful for you to experiment with.

For the record: GNOME applets all open just fine after purging acpid from the system, without pci=routeirq. But the machine hangs about 2-4 times in an 8-hour workday, under 2.6.18 final as well. Again, a separate problem, for which I'll open a separate bug. I'm attaching the dmesg and /proc/interrupts outputs for those not interested in browsing to lyre.mit.edu. Again, any help on config options which will work on both ACPI and non-ACPI machines would be much appreciated. -Adam
this sounds like the original bug got fixed, and this can be closed ?
The original bug was not fixed. Getting networking to work still requires acpi=off and preventing GNOME crashes requires pci=routeirq. Furthermore, if I don't killall hald, the whole system hangs within about 10 minutes of booting. Then again, the most recent kernel I've tried on this machine is 2.6.18. In the next week or so I'll try 2.6.21 and see how it fares.
Adam, is it still the same with latest kernel? The acpi=off interrupts snapshot doesn't show any ethX devices configured.
