MPSS Unable to start

[Christopher_R_3]

Hello, my Xeon Phi was working for about a month and suddenly it has stopped working. Using the Intel MPSS Debugging Flowchart for Linux I followed the steps down and then across the bottom to eventually to resetting the configuration. Unloading works, cleanconfig gives no message, and then initdefaults gives:

[Warning] mic0: Generating compatibility network config file /opt/intel/mic/filesystem/mic0/etc/sysconfig/network/ifcfg-mic0 for IDB.
[Warning]       This may be problematic at best and will be removed in a future release, Check with the IDB release.

Thus I have attached the micdebug log file as requested. Thanks in advance for any help. It's bizzare that it was working and now it's seem by the computer but the service cannot start, must be driver issues?

the attached file is empty, hence it is impossible to tell what it failing here. Can you upload it once more?

Sorry about that, permissions issues. It should be able to be read now.

the mic kernel module is not loaded. Most likely you rebooted the box and a new kernel came into effect (kernel-3.10.0-327.4.4.el7.x86_64) for which the mic.ko file is not loaded. Reinstall the mpss-modules-3.10.0-229.20.1.el7.x86_64-3.6-1.x86_64 package to update the 'weak-updates' link. Alternatively, type

cd /lib/modules/3.10.0-327.4.4.el7.x86_64/weak-updates
ln -fs /lib/modules/3.10.0-229.el7.x86_64/extra/mic.ko
depmod -ae

(hunt for the mic.ko module in /lib/modules) and then retry starting the mpss daemon.

Reinstalling the mpss driver worked. Thanks.
