The kernel module is made up of two threads that run every 1 ms. I have also made use of the rtpc dispatcher in rtnet to dispatch control messages from a netlink socket to the RT part of my kernel module. The problem is that when loaded the threads get suspended due to exceptions: Xenomai: suspending kernel thread b929cbc0 ('tt_upgw_0') at 0xb929cbc0 after exception #1792 or Xenomai: suspending kernel thread b929cbc0 ('tt_upgw_0') at 0x0 after exception #1025 or Xenomai: suspending kernel thread b911f518 ('rtnet-rtpc') at 0xb911f940 after exception #1792 I have ported the "gianfar" driver from linux to rtnet. The versions and hardware are listed below. The errors are most likely due to faulty software on my part, but i would like to ask if there are any known issues with the versions or hardware i'm using. I would also like to ask if there are any ways of further debugging the errors as i am not getting very far with the above messages. System info: Linux kernel: 2.6.29.6 i-pipe version: 2.7-04 processor: powerpc mpc8572 xenomai version: 2.5.3 rtnet version: 0.9.12 -- /Jesper
