daftykins: Your issue is there is no handler so you won't find anything in debug/irg for it:
[ 167.279809] do_IRQ: 1.35 No irq handler for vector HOWEVER, you should be able to find which target device is responsible by searching for matching Target: value, e.g. something like: $ grep -l 'Target: 1' /sys/kernel/debug/irq/irqs/* Examine/report the matching targets which should help identify the PCI bus *device* id (e.g. "device: 0000:00:16.0" in the report for irqs/126). Correlate that to the output of: $ lspci -nnk >From our previous IRC discussions you already know I believe it is the NIC since these reports only start once the NIC interface moves to UP state. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
