I've just tested once again the card with ubuntu, now I'm 100% positive it
works (i.e. the e1g44etblk was the only wired port during iperf, eth0 was
disconnected).
It works with ubuntu 10.04 server:
kernel 2.6.35-24-server
igb version 2.1.0-k2
It remains to be seen where the problem comes in SL (tested kernel:
2.6.32-71.18.2.el6.x86_64)
I'll see if I can compile kernel version 2.6.35 on SL or if the problem is
linked to my boot parameters (noapic acpi=off).
Hi Raimondo,
Thank you for keeping this m/l updated with the results of your
experiments. I would suggest the following steps:
(1) Check the Red Hat bug tracker for any related issues.
(2) Review the need for your current boot parameters.
(3) Build your own testing kernel from the latest stable long-term
support tarball (linux-2.6.35.12.tar.bz2).
Regards,
Alan.
Hello Alan,
I had no time in the last few days to go back to my servers.
Today I compiled my own kernel, version 2.6.38.2 (I compiled before
reading your comment about long term kernel support)...
I booted on one server and the very first test seems encouraging: I
can boot without the previous flags "acpi=off noapic" and finally the
pci-e network card work as supposed:
iperf -s (on a bonded interface)

Where eth8 and eth9 are in the second pci-e e1g44 card.
If tomorrow's tests will confirm further, I'll need to run to run a
custom kernel for the time being, until the el6 kernel are ok with my
hardware.
I'll see maybe for a kernel with drbd included, that would be really nice.
Regards and thanks for the help.
Raimondo
