The distro is Scientific Linux 3.4-Beryllium. I've compiled a 2.6.15 patched with rtai3.3 "hal-linux-2.6.15-i386-1.1-03.patch".
RTAI testing goes fine.
I've installed RTnet svn-version number Revision: 1019 (Last Changed Date: 2006-08-03 13:17:59 +0200 (gio, 03 ago 2006).
The host has got two Realtek Net adapters:
(from lspci)
01:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)
01:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
the drivers are
(from modprobe.conf)
alias eth0 8139too
alias eth1 r8169
The master node is 10.0.0.2 and is working fine on the same switch, waiting for this slave.
I created /dev/rtnet.
I have done rmmod for net adapters drivers and loaded rtai modules with:
initRTNet.sh
---------------
#!/bin/bash
ifconfig eth0 down
ifconfig eth1 down
rmmod r8169
rmmod 8139too
insmod /usr/realtime/modules/rtai_hal.ko
insmod /usr/realtime/modules/rtai_lxrt.ko
insmod /usr/realtime/modules/rtai_sem.ko
insmod /usr/realtime/modules/rtai_rtdm.ko
my rtnet.conf

When i use 01:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10) - eth0
"rtnet start" works but "rtnet stop" causes kernel panic.
What's the problem?
Furthermore i can't use the gigabit ethernet.
When I try to use the gigabit adapter, eth1, i write in rtnet.conf
...
# RT-NIC driver
#RT_DRIVER="rt_eepro100"
#RT_DRIVER="rt_8139too"
RT_DRIVER="rt_r8169"
#RT_DRIVER_OPTIONS="cards=1,0,0,0"
RT_DRIVER_OPTIONS="cards=0,1,0,0"
