Hi,like other users I have the problem that my system freezes when I run ./rtnet start.
When the system freezes the second and the third keyboard leds flash.
I analyze the problem and the error is when the rtcfg.ko module is loaded. I locked in /proc/interrupts file that no IRQ conflicts with my ethenet card are presents.
My configuration is linux kernel 2.6.24.7, rtai-3.6.2 and rtnet-0.9.11.
My /proc/interrupts file is:
CPU0
0: 3177531 IO-APIC-edge timer
1: 3478 IO-APIC-edge i8042
2: 0 XT-PIC-XT cascade
3: 2 IO-APIC-edge
4: 2 IO-APIC-edge
8: 0 IO-APIC-edge rtc

NMI: 0 Non-maskable interrupts LOC: 3177358 Local timer interrupts RES: 0 Rescheduling interrupts CAL: 0 function call interrupts TLB: 0 TLB shootdowns TRM: 0 Thermal event interrupts SPU: 0 Spurious interrupts ERR: 0 MIS: 0 and my network device has IRQ 18.My ethernet card is a RealTek RTL8139, but i try using a 3com with rt_3c59x.ko module, and the problem is the same. My CPU is an AMD Athlon(tm) 64 Processor 3500+, all software is compiled in 32bit. Gcc version is 4.3.3.
Finally i paste my rtai config file:
