hi,
I have the latest rtai-rtnet versions and a 2.6.14.3
kernel version
when I launch the rtai-rtnet example I have a
segmentation fault.
Also rtnet doesn't want to unload => reboot machine to
get it off.
here is my manual launching script
ifconfig eth1 down
rmmod e100
mknod /dev/rtnet c 10 240
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
insmod /usr/local/rtnet/modules/rtnet.ko
insmod /usr/local/rtnet/modules/rt_eepro100.ko
insmod /usr/local/rtnet/modules/rtipv4
/usr/local/rtnet/sbin/rtifconfig rteth0 up 10.0.0.1
netmask 255.255.255.0
/usr/local/rtnet/sbin/rtroute solicit 10.0.0.2 dev
rteth0
and here is the stack of dmesg for simpleserver ( the
2 others have the same problem):

When I lunch a lxrt program under rtai without rtnet
no problem to report.
So any idea: wrong compilation, wrong files, .....
Thanks,
Cedrick ROCHET
