suspend_stats looks better now:
# cat /sys/kernel/debug/suspend_stats success: 8 fail: 0 failed_freeze: 0 failed_prepare: 0 failed_suspend: 0 failed_suspend_late: 0 failed_suspend_noirq: 0 failed_resume: 0 failed_resume_early: 0 failed_resume_noirq: 0 failures: last_failed_dev:
last_failed_errno: 0 0 last_failed_step:
However the board is still automatically returning from resume (I haven't entered any char in the console)
