Comment 1 Ben Widawsky 2013-12-23 18:36:47 UTC 
Can you please try reverting 7c9c4b8f5dfe224ce587a470ce8817214c92271e from the kernel and see if the problem goes away.

If this fixes the problem: the return value is unimportant, my vote is to simply modify the test to not care about the return value.
