Reboot after going to suspend

[zsoerenm]

I tried to build this ROM on my own.
Everything is working fine as long as the HTC M7 is not going to suspend. So if it is connected to a PC via USB or if it is used as a Wifi hotspot this ROM works fine. However, as soon as the HTC goes to suspend (deep sleep), this build will reboot.

I tried to debug the error. These are the last lines of proc/last_kmsg:

This isn't very informative so I set no_console_suspend to debug with:

echo N | tee /sys/module/printk/parameters/console_suspend

After unplugging the USB cable again and waiting for the HTC M7 to suspend and restart, this is the proc/last_kmsg

It tries to go to suspend twice. I cannot see a clear error except msm_mpm_irqs_detectable: cannot monitor irq=261 (null).
How would you debug this @TARKZiM ?
I would be happy to dive deeper to get this device working.

I observed something interesting:
I rooted the devices with Magisk and installed Kernel Adiutor. If I disable all cores excepts the first one, the M7 won't reboot, when going to suspend. Any hints to resolve this issue will be appreciated.

I finally found the error. mpdecision could not start correctly, due to sepolicy.
I tried to start mpdecision manually with start mpdecision and the dmesg output was the following:

init: Control message: Could not ctl.start for 'mpdecision' from pid: 2741 (start mpdecision): File /system/bin/mpdecision (labeled "u:object_r:system_file:s0") has incorrect label or no domain transition from u:r:init:s0 to another SELinux domain defined. Have you configured your service correctly? https://source.android.com/security/selinux/device-policy#label_new_services_and_address_denials

I set selinux to permissive and now it isn't rebooting anymore.
@TARKZiM do you know how to set the sepolicy correctly?
