Sorry for pumping this old topic, but it needs some clarification:
For all of you who find this thread via search engines because you are looking for sporadic crashes on Xenomai PowerPC in relation to task switches: This patch does not fix the problem - at least not in our case. After several years, the problem suddenly appeared with us, as we are now increasingly using the Ethernet interface on our old product. Maybe the new interrupt load triggers this old bug.
There is a patch in Xenomai 3 which removes the buggy feature because of problems with the MMU. The only way to fix these sporadic crashes is to disable the switch (CONFIG_XENO_HW_UNLOCKED_SWITCH=n).
