[dpdk-users] Dell PowerEdge CPU IERR caused by DPDK 16.07

["Norbert Nyakó" <norbert.nyako@gmail.com>]

Hi,

We have two Dell R520 machines with the same configuration but
different Linux kernel versions [1][2]. I've compiled DPDK 16.07,
loaded the igb_uio and rte_kni kernel modules and configured the
machine to use the pmd for the 82598EB ethernet card.
As soon as I ran the testpipeline sample application on one of the
servers it stops responding  and on the LCD info screen and in the
logs CPU IERR error messages appear. After rebooting the error message
disappears. Does anyone have the similar problem? What could be the
root cause of this?

Thank you in advance!

Best regards,
Norbert
