Instability in ALL stable and LTS distro kernels (IRQ #16 being disabled, PCIe bus errors, ath10k_pci) in Dell Inspiron 5567

[Bandhan Pramanik]

Hello Askar,

I appreciate your response. However, we're mainly trying to find out
exactly 'why' this problem occurs. You might say that it's some kind
of "Root Cause Analysis," so that this error goes away from the
Inspiron laptops once and for all. If you keep on reading the messages
in the other thread, you'll realise just how deep this error goes.

But still, thanks a lot for the response.
