Ok, no 4.4 kernel + your patch this time, USB disconnected, LCD
blanked, but wifi connected and X session running on inactive vt. GSM
connected to network.
It seems like I have rather lot of blocking bits:

cm_idlest1_core changes periodicall often, to 00218072. The rest seems
constant.
I'm using script below:
#!/bin/bash
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
sudo mount /dev/zero -t debugfs /sys/kernel/debug/
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode
sudo cat /sys/kernel/debug/pm_debug/count
. Does it mean that more than 5 devices block the suspend?
Best regards,
Pavel
