After a kernel bisect, it was found that reverting the following commit resolved this bug: commit 68d929862e29a8b52a7f2f2f86a0600423b093cd Author: Matthew Garrett Date: Sat Mar 2 19:40:17 2013 -0500 efi: be more paranoid about available space when creating variables The regression was introduced as of v3.9-rc2, but it also made it's way into the stable trees(Commit 9f677cf in v3.8). I see the following commit was introduced to address this issue: commit 31ff2f20d9003e74991d135f56e503fe776c127c Author: Matthew Garrett Date: Mon Apr 15 13:09:47 2013 -0700 efi: Distinguish between "remaining space" and actually used space However, the issue still in 3.9.4, 3.10-rc3 and v3.8.13 after backporting 31ff2f2. I see that you are the author of this patch, so I wanted to run this by you and see if reverting commit 68d9298 is an option. There are several folks reporting this, so it should be easy to collect any additional data/information or perform testing, if needed.
