Subject: [dpdk-dev] EAL : Input/output error on DPDK 1.7.1
Date: Thu, 16 Oct 2014 23:34:37 +0530
Message-ID: <BLU182-W15F7C4FD2419C15D56377ABCAB0@phx.gbl> (raw)

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
