Title:
Slow flood of do_IRQ: No irq for vector
Status in linux package in Ubuntu:
Confirmed
Bug description:
Every few seconds I get something like this in my dmesg:
[44984.933221] do_IRQ: 1.34 No irq handler for vector
[44986.933976] do_IRQ: 1.34 No irq handler for vector
[44991.935614] do_IRQ: 1.34 No irq handler for vector
[45004.938590] do_IRQ: 1.34 No irq handler for vector
[45005.939002] do_IRQ: 4.34 No irq handler for vector
[45034.949161] do_IRQ: 4.34 No irq handler for vector
[45051.954569] do_IRQ: 4.34 No irq handler for vector
[45058.956019] do_IRQ: 4.34 No irq handler for vector
[45062.957727] do_IRQ: 4.34 No irq handler for vector
[45063.958204] do_IRQ: 4.34 No irq handler for vector
[45073.961103] do_IRQ: 4.34 No irq handler for vector
The numbers vary. Some examples are 4.34, 4.36, 1.34, 0.33, 6.34,
7.33, 5.37. Eventually dmesg's ring buffer is full and my entire log
is just messages like above with varying #.## numbers.
I researched it and tried disabling irqbalance. It had no effect, the
messages continued.
The system is a Ryzen 2700X with B350 chipset on Asus Prime B350-PLUS.
I have 64GB of Kingston DDR4-2400 ECC memory and Samsung 960 PRO M.2
NVMe SSD, and an Intel I350-T4 quad port gigabit NIC. This issue never
occurred before installing 18.03 on the same hardware. No overclocking
whatsoever has ever been done to this machine.
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.
