Hey,
I observe continuous burst of I/O Errors, as indicated below, with the testpmd
application with DPDK 1.7.1.This seems to originate from
eal_intr_process_interrupts() function. I seemed to have setup the DPDK
prerequisites alright.
Another recent post seemed to suggest moving back to 1.7.0, however I would
like to persist with 1.7.1.
Any help/pointers in resolving this would be greatly appreciated.
Much thanks,Raghav
