RTAI-5 make hangs at self-calibrate.

Hi all,

I'm working on a new laptop (ASUS E402M) and trying to get RTAI to compile on it.

I am running kernel 3.18.22 - updated into what is otherwise a Slackware 14.1 install.  I have applied the hal patch and successfully compiled and booted my patched linux kernel.

When I go to my RTAI source tree, unpacked into /usr/src/<folder> symlinked to /usr/src/rtai and try to compile it (first make menuconfig to setup, and then make), it begins ok, and then gets to the part where it calls "/bin/sh ../../base/sched/selfcalibrate.sh x86", and then it just hangs there forever.

If I switch to another terminal, I can see that lsmod reports rtai_hal and rtai_tmpsched are loaded, and then that dmesg shows some messages that look ok from both the rtai_hal module and the rtai_tmpsched module.  Checking ps aux shows that the selfcalibrate.sh script is still running, and has called "/usr/src/rtai/base/arch/x86/calibration/.libs/lt-calibrate ../arch/x86/hal" which is also still running.  Along with a "tee tmp_output".

Looking at the tmp_output file in /usr/src/rtai/base/sched/ reveals an empty file.  Also running is [RTAI_KTHRD_SRVR].

I have tried both RTAI 5.0-test1.tar.bz2 as posted on the main page of www.rtai.org<http://www.rtai.org>, and also tried ShabbyX's github master tree.  Both fail the same way.

Anybody have any idea what's going on here?  I've compiled RTAI many times before without this problem occurring, but never on this hardware.

-Duane
