troubleshooting nonstop “No irq handler for vector” kernel messages
One of my servers is constantly spitting errors that look like the following:
The rate is frequent and mostly regular... I get very clear frequency spikes at intervals of 6, 16, 23, and 40 seconds with a whole bunch of other intervals thrown in there as well.
[99666.888463] do_IRQ: 8.33 No irq handler for vector
[99683.675836] do_IRQ: 8.33 No irq handler for vector
[99713.730939] do_IRQ: 8.33 No irq handler for vector
I don't have older dmesg output so I don't know whether a recent kernel upgrade may have triggered this or if it's been happening for longer than the current kernel. I know it wasn't happening 3 weeks ago (I happen to have dmesg logs from something else...). My first question is : how do I map the "8.33" here into something meaningful? All the googling I've done implies that this is some locally significant IRQ or process ID, but I've no idea where that mapping is stored.
