Problems installing MPSS on Centos 6.5

[Choonghun_S_]

I am trying to install driver to setup my intel xeon phi on centos 6.5.

I followed the getting started guide, installing MPSS-3.5.

but when I run "modprobe mic", I am getting the following message:

1. [root@WS mpss-3.5]# modprobe mic
2. Message from syslogd@WS at May 31 00:57:39 ...
3. kernel:BUG: soft lockup - CPU#0 stuck for 67s! [work_for_cpu:6250]

Any idea what is going on? any clue about what is happening?

Regards

which exact kernel version are you using (uname -a) ?

Try running 2.6.32-504-* at the very least.

Also, you might be bitten by a power supply issue, where the power supply is not capable of powering both the motherboard and the Xeon Phi (which can draw up to 300W) - install the sensors package and check the mobo voltages when powering up the card.

Hello JJK

Thank you for your reply

I was try again latest kernel version. But Same problem appeared.

1. [root@WS mpss-3.5]# uname -a
2. Linux localhost.localdomain 2.6.32-504.16.2.el6.x86_64 #1 SMP Wed Apr 22 06:48:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
3. [root@WS mpss-3.5]# modprobe mic
4. Message from syslogd@WS at June 01 01:37:59 ...
5. kernel:BUG: soft lockup - CPU#0 stuck for 67s! [work_for_cpu:6220]

It is power supply problem?
May be power supplier is insufficient?

Could you please run the script /usr/bin/micdebug.sh and send us the tar file it produces? If you wish, you may sanitize it to change things like machine names and network addresses to something generic. I don't believe those will be relevant here, but I will especially want to see the log files, the rpm listing and the lscpi outputs.
