Hi,
Atmel SAMA5D31 boards no longer boot on today's linux-next. Bisected to:
commit 7d24068e144adc03b805806645d732cf79488717
Author: Wonhong Kwon <wonhongkwon@gmail.com>
Date: Tue Oct 6 10:10:20 2015 +0900
PM / hibernate: Move pm_init/pm_disk_init to late_initcall_sync
pm_init is being invoked by core_initcall and hibernate_image_size_init
calculates preferred image size (image_size) based on total pages
(totalram_pages). This totalram_pages can be modified during various
initcall-s phase and this can cause miscalculated image_size.
For example, when CMA is being used, init_cma_reserved_pageblock tries
to change the totalram_pages and this job is done during core_initcall.
In order words, the totalram_pages doesn't take CMA reserved pages into
account when image_size is calculated and it can be too small.
Move pm_init and pm_disk_init to late_initcall_sync so that it happens
after all other initcall-s change the totalram_pages.

Reverting it fixes the issue.

Looks like it is related to drivers calling at least the pm_runtime API
in their probe function, it is probably not just limited to Atmel SoC,
