Hello,
I am running openSUSE Leap 42.3 with kernel 4.4.76-1-default. And I see the following during hibernation:

The CONFIG_DEBUG_ATOMIC_SLEEP is enabled on openSUSE Leap 42.3 in the kernel default config: x86_64/debug:CONFIG_DEBUG_ATOMIC_SLEEP=y x86_64/default:CONFIG_DEBUG_ATOMIC_SLEEP=y SLE12 doesn't enable it on default config, that's why the BUG didn't show on SLE12 SP3. The root cause is that hibernation uses crypto API to generate signature in the context of sleep. The crypto_alg_lookup() calls down_read() that it calls might_sleep() the check the sleep can not be launched in a atomic sections. The hibernation signature verification can not pass the check. I am looking how to avoid this problem in hibernation code. Currently doesn't have good way to avoid this problem. At the moment, I suggest that either disable CONFIG_HIBERNATE_VERIFICATION or CONFIG_DEBUG_ATOMIC_SLEEP in kernel default config. -- You are receiving this mail because: You are on the CC list for the bug.

There are other errors beforehand, e.g. the known HD-audio problem, so let's clear it at first.
Could you try to pass probe_mask=0x01 to snd-hda-intel module? Create /etc/modprobe.d/60-hda.conf containing the following line:
options snd-hda-intel probe_mask=0x01
Well, sound-related messages dissipated. -- You are receiving this mail because: You are on the CC list for the bug.

Every other time the resuming just hard-freezes the whole system when showing screen-locker. I think it is related to 1051060. When the system survives resuming I see BUG:
So, the hibernation is success even you saw the "BUG:" stack dump? Base on the code in ___might_sleep(), it should not blocks hibernation. It just print out the "BUG" message. -- You are receiving this mail because: You are on the CC list for the bug.

Yes, I see this stack after successful resuming.
Base on the code in ___might_sleep(), it should not blocks hibernation. It just print out the "BUG" message.
So, then we probably can just ignore them, but they look scary enough. -- You are receiving this mail because: You are on the CC list for the bug.

I agree. I am thinking to create a new system state like SYSTEM_SLEEPING to avoid the checking logic in ___might_sleep(). I still need to check the scope and it may not accept by upstream. -- You are receiving this mail because: You are on the CC list for the bug.
