IRQ not handled on my Acer Aspire R3-131T

[Florian Dollinger]

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,

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.

Thanks in advance!

P.S: I would appreciate it if you could CC me personally at
