We have a Xeon Phi Coprocessor, firmware version 2.1.01.0375. Every time we restart the mpss service we have to remove the mic packages from the host and install them again to bring the mic back online. Otherwise it hangs and the only way I can see something, is connecting to the mic console using minicom. Here's what I can see repeating over and over in the mic console:
[ 842.813622] INFO: task kworker/u:0:5 blocked for more than 120 seconds.
[ 842.813643] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Installed packages in our system (SLES11 SP2):
Before the last driver upgrade, I was able to restart the mpss service without any problem. Has anyone had the same issue?
Thanks in advance.
