Re: RTAI 5.0-test2 released

If the problem is related to a lock due to many modules removal it is difficult for me to say anything, especially in view of the use of a virtual env.
I've just a question: does the same happens out of a virtualization?

Thanks, Pierangelo!  The new cross calibration stuff is great, really
helps my work flow.

However, i'm having trouble running tests in a virtual machine.  After
several load/test/unload cycles, the machine locks up, with no helpful
kernel messages on the console or in dmesg.

I'm *not* trying to use virtual machines for actual realtime workloads,
i'm just using it for correctness tests of my realtime application.  For
actual work i run the application on a bare-metal rtai machine.


I'm using a Vulcano CVS snapshot from 2016 May 12, there have been no
checkins since then.

I'm using Linux 3.18.20, and hal-linux-3.18.20-x86-6.patch.

My kernel config and my rtai configure command is here, along with a
dmesg showing boot & rtai load:
http://highlab.com/~seb/rtai/vm-problem.2016-06-23/

A debian package archive (for Debian Jessie) with the kernel debs and
rtai-modules debs is here:

deb http://highlab.com/~seb/linuxcnc jessie main

The packages to install to see this issue are
linux-image-3.18.0-1-rtai-686-pae (or -amd64) and rtai-modules-3.18.0-1.


I'd appreciate any help debugging this.  I'm perfectly willing to run
any tests you suggest.
