Well, I jumped to a conclusion too soon on the ACPI, that was a wrong
statement (wishful thinking), I recreated the issue even with ACPI off
This time the problem statement is more narrowed down.
1. dpdk is enabled on the interface, interfaces bound to igb_uio
3. kill the process using dpdk
3. rm
So looks like I figured it out .. I came across this bug reference
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=728692 and thought of
checking out my problem with ACPI turned off. And with ACPI turned off, the
problem doesnt happen. So theres something that the igb driver is not happy
about wh
Nothing in dmesg .. The ethtool was just a side-observation, the biggest
problem was that after unbinding from igb_uio and rebinding to igb, if I

All,
I have a Xeon machine with linux kernel 3.14 and dpdk 2.0, I have 6 ports
of which 4 are igb and 2 are ixgbe drivers .. I use the python script in
the dpdk distribution to bind and unbind the ports. I unbind them from
linux and bind to igb_uio, dpdk works just fine, then after a while I
