Problem running latency from showroom

[Donato Azevedo]

Mr Mantegazza,

this is the output of dmesg after I run ldmod:

Nov  1 12:12:39 linux-lec kernel: I-pipe: Domain RTAI registered.

Nov  1 12:12:39 linux-lec kernel: RTAI[rtai_msgq]: loaded.
Nov  1 12:12:40 linux-lec kernel: rtai_mq: Unknown symbol rt_trigger_signal
Nov  1 12:12:40 linux-lec kernel: rtai_mq: Unknown symbol rt_request_signal_
Nov  1 12:12:40 linux-lec kernel: rtai_mq: Unknown symbol rt_release_signal
Nov  1 12:12:40 linux-lec kernel: rtai_mq: Unknown symbol rt_wait_signal

So it seems it is missing those symbols...
I grep'ed the soruce dir, and signal.c EXPORTs these signals.....

grazie mile!
