--- Comment #8 from José Pekkarinen koalinux@gmail.com --- I'm afraid I reproduced this again using the kernel 4.17.2 where I see the following commit:
commit 9ca5a2ae4259e7aec8efb0db0f6ec721a6854c54 Merge: bee797529d7c c62ec4610c40 Author: Linus Torvalds torvalds@linux-foundation.org Date: Thu May 24 08:49:56 2018 -0700
Merge tag 'pm-4.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fix from Rafael Wysocki: "Fix a regression from the 4.15 cycle that caused the system suspend and resume overhead to increase on many systems and triggered more serious problems on some of them (Rafael Wysocki)"
* tag 'pm-4.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / core: Fix direct_complete handling for devices with no callbacks
I'll attach the boot process with the traceback soon.
