Because it may not be safe to use show_stack() from RT context (for
instance, the print_symbol function to print symbol names need to take a
spinlock when a symbol is defined by a kernel module, and this spinlock
is not rt-safe). Anyway, the error message normally prints the PC of the
error.

Could you give us the exact error messsage? The version of Xenomai, the
Linux kernel, the version of the I-pipe patch you use?
