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?
