Hello Pratyush,

A kernel bug report was opened against Ubuntu [0].  After a kernel
bisect, it was found that reverting the following commit resolved this bug:

commit a40178b2fa6ad87670fb1e5fa4024db00c149629
Author: Pratyush Anand <pratyush.anand@st.com>

    USB: Fix persist resume of some SS USB devices

The regression was introduced as of v3.17-rc1.  The regression still
exists in the 3.18-rc3 mainline kernel, and has made it's way into the
stable kernels.

I was hoping to get your feedback, since you are the patch author.  Do
you think gathering any additional data will help diagnose this issue,
or would it be best to submit a revert request?
   

Thanks,
   
Joe
