Problem with Realtime Kernel and Ethernet Card

Problem with Realtime Kernel and Ethernet Card

[Matthias Söllner]

Hello,
I installed a RT-Preempt Kernel in Debian 6
as shown on
http://pengutronix.de/software/linux-rt/debian_en.html

I have a DELL Precision T1600 with onboard network card and additional
PCI network-card.

The onboard card is a Intel® 82579LM Gigabit-LAN.

I used linux-image-2.6-rt-686 from Pengutronix APT repository.

Installation worked fine, I can boot my debian with both kernels.

If I boot normal debian kernel i have eth0 and eth1. both cards work fine.

But if I boot RT-Preempt-Kernel the  internal network card is not shown
and I only have eth0.

With normal debian kernel intel e1000e driver is loaded.

What can I do to make my internal network card function properly with
realtime kernel ?


I tried to compile the intel network driver myself. But where to I get
the right kernel-headers for my RT-Preempt-Kernel?

Any hints?
Thanks a lot
Matthias

It looks like you're using an old version of the realtime kernel, and
the maintainer has neglected to package headers for it. (see:
http://debian.pengutronix.de/debian/pool/contrib/l/linuxrt-latest/ ).
If your CPU will support a 64-bit kernel, I suggest trying one of the
3.0 kernels. It's more likely to have your network driver built in,
and there's a matching linux-headers package if you need it.

That's an 2.6.33.7.2-rt30 kernel. For amd64 there are also newer kernels
available on debian.pengutronix.de (3.0 series) and Debian experimental
(3.2 series). If possible I'd recommend the newer versions.

Normal Debian kernel means 2.6.32 I guess? 2.6.32-36 added a backport of
the e1000e driver from 2.6.38 and this backport is not included in the
2.6.33.7.2-rt30 package because it branched from the Debian kernel
before 2.6.32-36.

They should be available on debian.pengutronix.de, too. Just install the
matching headers package, in your case probably
linux-headers-2.6.33.7.2-rt30-1-686.

Ok.
Where do I get a 3.0 Kernel with included preempt-Patch for installing
in Debian 6.0?

By the way, is there any package which includes a Kernel with included
Preempt-Patch for use in Ubuntu 11.10 as it was available for ubuntu
8.04 (linux-rt)?

Thanks

Matthias

if you're on amd64 install linux-image-3.0.0-2-rt-amd64 from
http://debian.pengutronix.de/debian sid main. That is what was in Debian
while it had 3.0 and updated to 3.0.12-rt30 and 3.0.14 which IIRC
matches 3.0.14-rt31.

Nothing I'm aware of. Maybe the debian kernels just work?!

I can't find the package in
http://debian.pengutronix.de/debian sid main

Added it to /etc/apt/sources.list, and made a sudo apt-get update.
But the package is not there.

What am I doing wrong?

Thanks
Matthias

What is the output of $(dpkg --print-architecture)?
debian.pengutronix.de only has the 3.x-rt kernels for amd64. The same is
true for Debian itself BTW.

Re: Problem with Realtime Kernel and Ethernet Card

[Matthias Söllner]

Ok, this was the problem to see the package. I installed a fresh
debian-squeeze 6.04 stable for amd64 and now I can find the package.

But if i do an sudo apt-get install I get the following error:

Die folgenden Pakete haben unerfüllte Abhängigkeiten:
 linux-image-3.0.0-2-rt-amd64 : Hängt ab von: linux-base (>= 3~) aber
2.6.32-41 soll installiert werden
                                Empfiehlt: firmware-linux-free (>= 3~)
soll aber nicht installiert werden
                                Beschädigt: initramfs-tools (< 0.99~)
aber 0.98.8 soll installiert werden


Any suggestions?

Thanks
Best Regards
Matthias

You need to install linux-base and initramfs-tools from wheezy.

That is add

	deb http://cdn.debian.net/debian/ wheezy main

to your sources list and install/upgrade the needed packages.
