Dear all,
I just received my brand new computer with the Intel Xeon Phi. I followoed the instructions on the MPSS readme and booting files but the card behaves randomly. Sometimes it enters the reset failed mode, sometimes not. It takes a loong time (if ever) to reset using
[jrbcast@localhost ~]$ sudo micctrl -r
Also, I cannot see anything through the micinfo command whenever the card is on the READY state even when the MPSS service is started as shown:
[jrbcast@localhost ~]$ /opt/intel/mic/bin/micinfo

Also, the micsmc command does only show that cards are disconnected !!. I attach a file with the dmesg and all the command sequence I have followed to write this mail.
In another thread I read that these Post codes (obtained through dmesg command) meant something was wrong with the memory. Should I RMA the card?:
MIC 0 Resetting (Post Code 3d)
MIC 0 Resetting (Post Code 3d)
MIC 0 Resetting (Post Code 3d)

MIC 0 Resetting (Post Code 3d)

Thanks in advance,

Hi Jose, I posted earlier to your post in the collateral thread (http://software.intel.com/en-us/forums/topic/366599) but it is more appropriate to continue the discussion under this post.
I looked through this post and the attachment and do not see anything to suggest the card did not function properly at least when the posted information was collected. The Engineer I inquired with indicated 3E is a normal state the card enters during reset and the time spent in that state varies with different cards; however, from your description it sounds plausible there could be a HW issue with the card.
If you purchased your system through an OEM then contact them to determine if a replacement card can/should be provided.
I realize that is not much help, but I hope it helps some.

thanks Kevin,
I forgot to mention that I am running under CentOS 6.3 with the original kernel, no updates. Nevertheless, after waiting for more than 300 seconds for a restar, and not being able to query through mic info, I am pretty sure someone is not working well. I have already contacted my supplier. Lets ths develops.
bests,
jose
