[Kernel-packages] [Bug 1592541] Re: trusty kernel with virtio-blk oops
I built a lts-utopic test kernel with a pick of 764f612. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1592541/ Can you test this kernel and see if it resolves this bug?

Re: [Kernel-packages] [Bug 1592541] Re: trusty kernel with virtio-blk oops
Having posted, I see that this is actually a utopic kernel that oopsed (3.16.0-71-generic) However, the oops stack is still possible on trusty, the blk-merge code in 3.13 doesn't include the fix that appears in the vivid kernel.
