IRQ not handled -> hundreds of errors in dmesg

Hi there,
i have a problem which is nearly the same as Christian postet at the kernel mailing list here: http://lkml.iu.edu/hypermail/linux/kern … 03006.html

The errors in the kernel log look like this:

[    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

The problem is, there are hundreds or thousands of it - everytime exactly the same.
Looks like the error don't affect the usability of the system, but my dmesg is useless^^

Before you ask: It has nothing to do with PM on my system!
Also, i already updated my BIOS to the latest version.


Here are my logs as aked for in the mailing list

LTS (everything is fine)
-> dmesg: https://pastebin.com/3XnFtpgB
-> interrupts: https://pastebin.com/XdN1juKb
-> pins: https://pastebin.com/hwX3vvZN

4.13.12 (what a mess!)
-> dmesg: https://pastebin.com/5fhLM0sn
-> interrupts: https://pastebin.com/FLELSX3Q
-> pins: https://pastebin.com/uPes8624

Cheers, Flo

Re: IRQ not handled -> hundreds of errors in dmesg

The other report lead to a patch:
https://patchwork.kernel.org/patch/9405629/
https://git.kernel.org/pub/scm/linux/ke … 1fe87983f3

The patch also suggests to update your BIOS.
Is this a dual boot (do you also have a windows installation)?

Re: IRQ not handled -> hundreds of errors in dmesg

unfortunately my bios is up to date...
looks like the patch is concering a PM problem, this is not the case at my machine.

yes, it is a dual boot system with windows on the other partition. why do you ask?

Re: IRQ not handled -> hundreds of errors in dmesg

If you're getting IRQ trap errors, I've had this issue and found a solution.
[pinctrl_cherryview] is the module in question and when blacklisted, solves the problem.
Add this to your bootloader options:
modprobe.blacklist=pinctrl_cherryview
Then update the kernel modules with:
sudo mkinitcpio -p linux && reboot
