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!
