Bug#932304: do_IRQ: 0.37 No irq handler for vector

["Miguel A. Vallejo" <ea4eoz@gmail.com>]

Same problem here since march using the kernel 4.19.16-1: do_IRQ: 0.37
No irq handler for vector flooded the terminals making the system
unusable.

Now with 4.19.37-5 and same problem.

But for me this problem is triggered by the Arduino IDE. Everything
works fine until I start the Arduino IDE, and the flood stops once I
close the Arduino IDE.

I suspect it has something to do with the auto serial port discovery
in the Arduino IDE.

Hope this helps.
