Subject: IRQ not handled on my Acer Aspire R3-131T

Hi there!

My machine is an Acer Aspire R3-131T, the firmware installed is the 
latest (1.17, released 2017/01/04).

My problem is that my kernel log is overflooded with the following error:

[    5.356743] irq 173, desc: ffff9c9bb7b48800, depth: 1, count: 0, 
unhandled: 0
[    5.356745] ->handle_irq():  ffffffff9b0e0a90,
[    5.356747] handle_bad_irq+0x0/0x260
[    5.356748] ->irq_data.chip(): ffffffffc0713120,
[    5.356751] chv_pinctrl_exit+0x4533/0x413 [pinctrl_cherryview]
[    5.356752] ->action():           (null)
[    5.356753]    IRQ_NOPROBE set

You already discussed something similar last Year (Oct 2016) here:

Here are the same logs, which you also asked for at the discussion 
mentioned above.

LTS (everything is fine)
- dmesg:
- interrupts:
- pins:

4.13.12 (what a mess!)
- dmesg:
- interrupts:
- pins:

Thanks in advance!

P.S: I would appreciate it if you could CC me personally at 
answers/comments since I am not yet subscribed to the kernel mailing list.
