I built a test kernel with a cherry pick of commit c50bfd08. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1520427/

Can you test this kernel and see if it resolves this bug?

Thanks in advance!

I tested the above kernel in comment #2, it pass SMEP/SMAP test and doesn't generate regression.

Thanks for the update. I will submit an SRU request for that commit.

Commit c50bfd08 does not pick cleanly in the Vivid(3.19) kernel. The 3.19 kernel does not have intel_fbdev_blank() or intel_fbdev_pan_display(). intel_fbdev_blank() was added by commit 03e515f7 in v4.1-rc1. intel_fbdev_pan_display() was added by commit d9a946b5 in v4.2-rc1.

Can you confirm where or not commit c50bfd08 is needed in the 3.19 Wily kernel? If it is, I can backport the commit.

Thanks in advance!

It looks like you already submitted an SRU request, so please ignore comment #4. And it looks like apw has performed the backport for #5.

I built a Vivid test kernel with the backport from Andy Whitcroft. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1520427/

Can you test this kernel and see if it resolves this bug?

Thanks in advance!

The kernel in comment #7 pass our SMEP/SMAP test and doesn't generate regression.
