Installation issue: 'modprobe mic' freezes server

jofre — Fri, 21 Jul 2017 11:53:00 GMT

Dear all,

I am trying to install mpss 3.8.2 on a OpenSuse Leap 42.2 (in principle equivalent to Suse12.2). It comes with a newer kernel that the one stated in the 'readme.txt' file.

So I proceed with the instructions found in 'readme.txt' file. Everything ok until
# modprobe mic

At that point the machine freezes.
I am using the following kernel:
$ uname -r
$ 4.4.27-2-default

The mic.ko is correctly at '/lib/modules/4.4.27-2-default/extra/mic.ko'

For information:
lspci | grep -i Co-processor
05:00.0 Co-processor: Intel Corporation Xeon Phi coprocessor 31S1 (rev 11)
42:00.0 Co-processor: Intel Corporation Xeon Phi coprocessor 5100 series (rev 11)

Ideas are more than welcome...

I'm not familiar with Mic cards in OpenSuse but I do know that cooling is a problem sometimes; it could very well be that when you do an "modprobe mic" that the cards become active, start generating too much heat and then the system shuts down to prevent damage.

Can you test with a CentOS 7 live CD to see if you can access both cards without any issues?

Finally, have you tried rebuilding the mic driver for your updated kernel? Intel does supply all sources files necessary to build your own kernel mod.

HTH,

JJK
