This patch hit next-20150519 in the form of commit 27a4c827c34a (fbcon: use the cursor blink interval provided by vt) and has caused boot failure on a handful of ARM platforms when booting a MMC root filesystem. This error was spotted by the kernelci.org bot on exynos5800-peach-pi[1] and Thierry and Daniel (Cc'd) have seen it on some tegra platforms too.
Thierry spotted this commit as a potential cause, and both Daniel and I have reverted and boot tested on exynos5 and tegra respectively and the boot panics disappear.
