this is (mostly) fixed in 2 commits, from the original bug (bug 1505564) kernel level commit 5a3a466ae3c86ad6b8fc36c2efc5f541ef0ed89e (from git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git lts-backport-vivid) partially fixes this problem, by using the console_may_schedule var correctly. The recent upstream commit 6b97a20d3a7909daa06625d4440c2c52d7bf08d7 (from upstream) completes fixing the problem, by setting console_may_schedule correctly.
