Running an Intel S2600ST motherboard with dual Gold 6148 I get this error regularly after the last kernel update I did.
The number before the dot seems to be a CPU number since I see many varied numbers and there's 40 cores/80 threads on my motherboard e.g. [Wed Dec 26 14:20:25 2018] do_IRQ: 14.216 No irq handler for vector [Wed Dec 26 18:35:32 2018] do_IRQ: 46.40 No irq handler for vector [Thu Dec 27 00:56:21 2018] do_IRQ: 15.55 No irq handler for vector (there are 37 of these over the last 2 weeks) There's no /sys/kernel/debug/irq/ folder The current kernel on "Ubuntu 16.04.5 LTS" I am using is "vmlinuz-4.4.0-140-generic" I updated from "vmlinuz-4.4.0-119-generic" (which was also 16.04 LTS) I've had this server for over a year and with the 4.4.0-140 update is the first time I've seen this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781016 Title: Slow flood of do_IRQ: No irq for vector To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781016/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
