Jeff,

I have a test kernel in 
https://launchpad.net/~centriq-team/+archive/ubuntu/lp1712580/  This 
kernel has patches to fix the Ubunt u bug 
https://launchpad.net/bugs/1712580

Could you also please reply-all and share the test case and test setup 
along with your test results on QDF2400 platform? I need to be able to 
verify that it works for other architectures as well, especially for 
amd64 and ppc64el because these patches impact the generic kernel.

Thanks
Manoj Iyer.
