Hello,
I port Ubuntu touch for LG L90 Dual and other derivatives. Currently, I'm trying to debug CPU lockup problem that appears when the system is going to suspend. The symptom is that when I placed the phone for a while, the phone will sometimes not respond to the power button. Very rarely, the phone will respond to the power button after a few seconds, which will place some log in kernel ring buffer that a CPU lockup occurs. Unfortunately, I've lost those logs. If not, I have to reset the phone by holding the power button and losing all log in kernel ring buffer, including /proc/last_kmsg.
This problem appears when I make the system run init.zetaw.post_boot.sh when the system finished booting. For those who don't familiar, this script makes final settings for CPU governor and power saving features.
I've tried searching for debugging interfaces for this device on Google but found nothing. I would like to ask if there's any debugging port on this device. Like, UART port of something similar. Or if anyone have any technique for this problem, please tell me.
Thank you.
