I am testing on exynos_defconfig with some stuff enabled (nothing
special: regulators, chargers, PM_ADVANCED_DEBUG, extcon etc.). However
sometimes I also see hangs related to MMC. But I believe this issue is
present for some time and is not related to my DELAYED_RESET_ASSERTION
changes.

Maybe you could try to boot with "no_console_suspend loglevel=7" and see
when the suspend fails?

Best regards,
Krzysztof
