Hi, As Philippe has been suggesting it, I've been testing v2.4-rc4 on x86 (not favourite board though :) with the RTAI skin (not my favourite skin too). Anyway, a legacy RTAI application which was fine with v2.3.2/2.6.20, is now freezing the box randomly in the first 30 seconds. On the other hand, the programs from the testsuite are running stable. So we may rule out a problem in the I-Pipe/kernel.
For the legacy RTAI application to load, the attached patch was necessary. The patch against ksrc/skins/rtai/shm.c is somewhat defeating the purpose of a lower XNCORE_PAGE_SIZE, so a better fix might be expected. The box is running FC5 on a pentium D, but kernel is compiled for UP. $ cat /proc/ipipe/version 1.10-09 $ cat /proc/xenomai/version 2.4-rc4 $ cat /proc/version Linux version 18.104.22.168 () (gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)) The kernel config file is attached. I'm currently stripping down the RTAI code out of the application in order to have a simple testbed reproducing the freeze. In the mean time, does anyone have a clue where to look particularly? TIA -- Stephane
