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

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)?

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?

Disable fast boot.

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
