Hello!
We are having trouble with "Illegal instruction" (illegal opcode) crashes
(dumping core) of two different Xenomai programs on different computers, occuring
approximately once every few days. Here are some perhaps relevant details...
Linux kernel version: 2.6.34
Which I-pipe release?
<snip>
So, the two cases look somewhat similar: The "Illegal instruction" is reported
around pthread_setcanceltype@plt; there are legal branch instructions there as well as at
the branch target locations; pthread_setcanceltype@plt is called from timed wait
functions (pthread_wait_np() and rt_task_sleep() resp.).
We would be grateful for suggestions how to analyze and cure the problem.
This looks like mm woes. Is CONFIG_XENO_HW_UNLOCKED_SWITCH enabled?
