-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1781016 Title: Slow flood of do_IRQ: No irq for vector Status in linux package in Ubuntu: Incomplete 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.
