Re: RTAI 5.0.1 calibrate program: BUG: unable to handle kernel paging request at 00007ffe78e450f0

Ciao,
please, beware of trolls. They are amusing, at times, but often they do 
not know what they are talking about.

The problem of calibration faults has been solved by the end of 
May-2017, thanks to a cooperation with Josef (Aßfalg).
The fix is 
in"https://www.rtai.org/userfiles/downloads/RTAICONTRIB/rtai-5.0.1.tar.bz2", 
to be 5.1, when we'll get a new RTAI repository, hopefully soon.

If you want to know more about it have a look at the following May-2017 
threads on the RTAI mailing list:

Not sure where he got the idea that it's so brilliant and to always grab the latest versions of his (ripped-off) code. RTAI 4.0.1 which I've based my stable tree of off has absolutely no issues.

The old calibration code worked so much better, literally "just works." RTAI 5 is not ready for production and is not stable by any means. I highly suggest avoiding anything above 5.0 until there's some more confirmed cases of it working in upcoming releases.
