If you have a dhcpcd running on eth0, there should be at least tx statistics progress during early interface start-up, even if you had IRQ troubles. You may want to check if there is dhcp running. > -So i look into /proc/interrupts, i can see : > 10: 1317604 153347 XT-PIC-XT sata_nv, eth0 > and the number of interrupts don't progress after i have run ./rtnet start. Just to be sure, check under /proc/xenomai/irq if IRQ 10 happens to be in use by some RT device (rteth0...) as well. Also check if the kernel log contains anything unusual around starting RTnet. Jan
