Re: [Kernel-packages] [Bug 1781016] Re: Slow flood of do_IRQ: No irq for vector
I have an APC UPS too. Great find. Who would have guessed an IRQ handling problem message from the kernel was due to a serial or USB device. Wow.

Exactly. It never happened in ubuntu 17.10. Started happening after installing ubuntu 18.04. Can't say I know exactly what kernel version 17.10 was up to, sorry. It was the standard one, whatever dist-upgrade would have gave me. I'll try the kernel version you proposed and update this bug after I try it.

Also, I had to disable selective suspend on USB in this version to prevent major USB issues, which was not required in 17.10, that might be related. My system seems stable, but spurious IRQs can't be good. I'd like to resolve this if possible.

I have almost the same issues, except I run Metacity, so it's not related to compiz, and in my case, the panic can happen at resume but it frequently happens when I (try to) restart or shutdown. It kernel panics with either black screen or text mode, with flashing numlock. Stack trace scrolls off the top, but the symbols clearly indicate it is executing in the wl driver.

I installed the packages (needed headers too), rebooted into and selected that version in grub, and so far it is passing my stress test that provokes gpu hangs, and no hang yet, which is great! Also, I haven't seen the warning yet (the ones I originally reported), but that happens durng normal operation and may never happen during stress. I'll use it normally for a bit and report what happens.
