This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- vivid' to 'verification-done-vivid'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

@timg-tpi
I reverted it on latest ubuntu-vivid, but there is variable dependency
with the other related commits, so I patched like below
it is better, but still dropping is there.
original 100 -> 0.3
below patch 100 -> 15~20

I built a Vivid test kernel with a cherry pick of commit 0d158852a. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1521053/ Can you test this kernel and see if it resolves this bug? If it does, we can submit an SRU request for that commit.
