Hi,
The continus burst of I/O Errors occured, as indicated below, when the helloworld application of dpdk2.2.0 example was running:
EAL: Error reading from file descriptor 13: Input/output error
EAL: Error reading from file descriptor 13: Input/output error
EAL: Error reading from file descriptor 13: Input/output error
EAL: Error reading from file descriptor 13: Input/output error
I installed the dpdk in virtual machine: centos7 + kvm. One NIC was bound to igb_uio mode.
And if I unbound the NIC to e1000, then no error happened with helloworld running.
I had tried updating the igb_uio.c according the following patch,but the error still existed.

Any suggestion is appreciated.
Best regards,
Guanghua
