mic0: lost

Hi !

I begin with Xeon Phi and MPI. After a lot of troubles, yesterday I managed to run MPI programs on symmetric mode (both host and co-processor) as well as directly on mic0 after ssh.

But today I have troubles again.

MPSS starts correctly and 3 minutes later the status of mic0 is lost and I can not reset it.

# micctrl -s
mic0: lost
# service mpss status
mpss is running

# micctrl -rw
          mic0: resetting
          mic0: reset failed

Even when everything seems to run fine I am not able to reboot or reset with micctrl. I never succeded in reseting or rebooting mic0 without rebooting my computer.

My hardware :

• motherboard : ASUS P9 X79E-WS
• processor : Xeon E5 v2
• co-processor : Xeon Phi 7120P (with a fan)

My OS : CentOS 6.5

A piece of micinfo output :

Flash Version : 2.1.02.0386
SMC Firmware Version : 1.14.4616
SMC Boot Loader Version : 1.8.4326
uOS Version : 2.6.38.8+mpss3.2

Thanks in advance.
