e1000 driver problem with Intel Pro/1000 MT adapter

e1000 driver problem with Intel Pro/1000 MT adapter

[Jos Vos]

Hello,

I have a problem with an Intel Pro/1000 MT 4-port card in a Supermicro
(non-HT) Pentium 4 system using RHEL3 (2.4.21 kernel "the RH way") with
the e1000 driver (I tried both the version supplied by RH and the
newest 5.5.4 driver):

(1)
With a non-SMP kernel, the whole system freezes instantaneously when
configuring one of in the four interfaces.

(2)
After disabling the USB controller, all interfaces can be configured,
but only one of them actually works.  Via the others, I can sent
packets, but do not receive incoming packages (possible IRQ problem).

(3)
Using a SMP-kernel, two of the four interfaces can be configured and
work correctly.  For the other two ports, ifconfig gives the
error "SIOCSIFFLAGS: Invalid argument".  Stracing ifconfig says:

  socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
  ...
  ioctl(4, SIOCSIFADDR, 0xbfffc210)       = 0
  ioctl(4, SIOCGIFFLAGS, 0xbfffc140)      = 0
  ioctl(4, SIOCSIFFLAGS, 0xbfffc140)      = -1 EINVAL (Invalid argument)

Stracing ifconfig for an interface that works shows similar lines,
but then the second SIOCSIFFLAGS ioctl succeeds.

Supermicro suggest to change the non-HT P4 CPU by a HT one, but I
personally do not believe that this will change the situation of the
SMP kernel as described above.

Any suggestions how to solve this are welcome.  I can provide more
information if needed.

Thanks,

<I am not the e1000 maintainer>

The error code for the ioctl most probably comes through
e1000_open
-> e1000_up
   -> request_irq

That + (2) + SMP suggests an irq routing issue due to a broken acpi
table ("suggests").

I would compile a (monolithic) recent 2.6.x to see its log and
give a look at http://acpi.sourceforge.net/dsdt/index.php (once the
ticket is opened at http://bugzilla.redhat.com of course :o) )

IIRC ACPI is disabled in the BIOS (not sure), but I'm using a
RHEL3 2.4.21 kernel that does not support ACPI at all (due to
the RH patches rebuilding the kernel with ACPI enbabled does
not work anymore)!

Well, I could do that, but the idea was to use this in a RHEL3
system, so ...

1 - Imho people at RedHat/wherever need more details (chipset, mobo,
    dmesg, lspci -vx, 2.4.21 savor ?).
2 - Testing recent 2.6.x will provide a different datapoint and a wider
    review: a few people use e1000 for interested things here but they
    do not necessarily have the resources to help with a specific vendor
    released kernel. The vendor can use the datapoint though.
3 - Comparing lspci and dmesg output for the different failure may give
    an hint.

Yes, ok, I might install RHEL4 beta or Fedora Core 3 on it next week
and see how that works.

The 4-port card has two 82546 dual-port controllers behind a PCI-X
bridge.  Your symptoms suggest interrupt routing didn't get setup
correctly for the controllers behind the bridge.  I've seen more than
one case where the BIOS gets this wrong.  The fix is to upgrade to the
latest BIOS.  Hopefully this is the fix for you.  :-)

For what it's worth, I've had good luck with a 4-port pro/1000 NIC
in a SuperMicro X5-DPAGG (dual xeon, PCI-X) motherboard.  I've tried it with kernel
2.4.27 and 2.6.9 so far...  For maximum performance, I needed to increase
the tx and rx descriptors to 2k, I believe this helps mitigate the extra
latency caused by the PCI-X bridge on the NIC...

Unfortunately, the latest BIOS for the MB is already installed :-(.

I just a prerelease of their next BIOS from Supermicro and that seems
to solve the problem!

I still have to boot the SMP kernel to get APIC working, in UP mode
incoming packets are not seen, but I can live with that.
