Serial_ir: bad irq number or handler

Noclue · March 6, 2018 at 9:47 PM

Hi,

I set up my Raspberry Pi to host Libreelec. Added a gpio-ir device on the standard input gpio, set the keymap according to the remote available to me and all worked well for two days.

Since this evening I am getting this:

Quote

serial_ir serial_ir.0: Bad irq number or handler

serial_ir: probe of serial_ir.0 failed with error -22

Checking /dev also shows there is no ttyS0.

What is going wrong? Any hint appreciated.

syslog available here: TsK

This is rather odd, serial_ir is nothing you'd be using on RPi.

That module is not included in default RPi kernel config but seems to be coming via the dvb drivers / media tree. Still, it shouldn't be loaded, even on x86 (where that driver is occasionally used) you need to manually load it via modprobe or modules-load.d

Could you check if you have something in /storage/.config/modules-load.d or /storage/config/autostart.sh that would load that driver?

so long,

Hias

Thanks for your response.

I did try again this afternoon and it seems that the PVR VNSI addon is the culprit.

After de-install and reboot the remote worked again.
