http://www.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/2.6/2.6.0-test11-bk11-netdrvr-exp2.patch.bz2

Cannot test before saturday ! but i will as soon as possible.

I saw that issue on a couple of dual CPU motherboards with integrated e1000. I
fixed it by passing the : noapic parameter on the linux boot.

Hello,
this is really a bug, i've got the problem with <b>2.4.25-rc1</b> kernel too ...
please correct this bug before 2.4.25 release.

With two e1000 on mainboard only one is detected and usable :(

2.4.21 kernel is ok but poor security.

noapic kernel parameter does not resolv this problem.

Board: Tyan S2707G2N (two gigabit ports)

This is the same problem with
2.6.0, 2.6.1 and 2.6.2 with and without noapic kernel param :(

Here is a strange thing:

lspci on 2.6.2 and 2.4.25-rc1:

00:00.0 Host bridge: ServerWorks: Unknown device 0017 (rev 32)
00:00.1 Host bridge: ServerWorks: Unknown device 0017
00:07.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27)
00:08.0 Ethernet controller: Intel Corp.: Unknown device 100e (rev 02)
00:0f.0 ISA bridge: ServerWorks CSB5 South Bridge (rev 93)
00:0f.1 IDE interface: ServerWorks CSB5 IDE Controller (rev 93)
00:0f.2 USB Controller: ServerWorks OSB4/CSB5 OHCI USB Controller (rev 05)

00:10.0 Host bridge: ServerWorks: Unknown device 0101 (rev 05)
00:10.2 Host bridge: ServerWorks: Unknown device 0101 (rev 05)


lspci on 2.4.21 (two e1000 works well):

00:00.0 Host bridge: ServerWorks: Unknown device 0017 (rev 32)
00:00.1 Host bridge: ServerWorks: Unknown device 0017
00:07.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27)

00:0f.2 USB Controller: ServerWorks OSB4/CSB5 OHCI USB Controller (rev 05)
00:0f.3 Host bridge: ServerWorks: Unknown device 0225
00:10.0 Host bridge: ServerWorks: Unknown device 0101 (rev 05)
00:10.2 Host bridge: ServerWorks: Unknown device 0101 (rev 05)
02:07.0 Ethernet controller: Intel Corp.: Unknown device 100f (rev 01)

On 2.4.21 there is a 02:07.0 device !

What could i do to help you resolving this problem ?

Hmmmmmm,
it seems to be not a "bug" in e1000 driver but in apic/acpi/smp/other (i'm sorry
i'm not a kernel hacker yet) ...

Here is a new information, with 2.6.2 it works well (two e1000 eth): i remove
acpi, smp and ioapic from kernel and my two e1000 works very well !

I try with 2.4.25-rc1 in 2 hours, more informations at this time.

is there a failure in the latest 2.4 or latest 2.6, or do they both work and 
we should close this?

thanks,
-Len

Please test 2.4.26 or 2.6.5 -- thanks, -Len 

This is the same problem with 2.4.26 Tyan S2707G2N with two gigabit ports !

With ACPI stuff in kernel only one e1000 card is detected and enabled.

If i remove all acpi stuff from kernel everything is OK.

This may be a duplicate of bug 1662 -- the infamous _BBN-0 bug. 
 
Please attach dmesg from ACPI+IOAPIC mode (where we see the failure) 
as well as the output from acpidmp,  available in /usr/sbin/, or in pmtools: 
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ 
 

still a problem in 2.6.6? 
If yes, please attach the info requested above. 
Also, please try "pci=noacpi" in 2.6.6. 
 
thanks,

no reply in a month, assuming this is a duplicate of bug 1662. 
If that turns out not to be the case, feel free to re-open.
