Could you please tell which QCOM SoC this board is based on?


Snapdragon 845 with kernel 4.9.x

Irqchip driver is "drivers/irqchip/irq-gic-v3.c". The kernel you are
using is msm-4.9 I suppose or some other kernel?

Yes, I am using customized version of msm-4.9 kernel based on Android.
And yes the irqchip driver is: irq-gic-v3, which I can see from config.

But, what I wanted to know is, how to find out which driver module
(hopefully under: /drivers/soc/qcom/) that register with this
irq_chip, is getting triggered at the time of crash ?
So, that I can implement irq_hold function for it, which is the cause of crash.


Hmm, since this is a bootup crash, *initcall_debug* should help.
Add "initcall_debug ignore_loglevel" to kernel commandline and
check the last log before crash.
