Hello, I create a small host to monitor the network. Asrock J3455B-ITX
motherboard, Intel Pro 1000 PT Dual Port PCI-E network card. After
starting the system, I receive messages on the console:
sched_ithd: 10 stray interrupts 22 on cpuXX
What can be a problem in this case and is it possible to solve it?
In the case when I turn on the polling mode for em0, the system stops responding for several dozen seconds in the loop.
Earlier I set options:
hw.tsc_cputimer_force="-1" <- hangs on boot in default configuration
