Can you elaborate what "should not happen" mean ? AFAIU nothing prevents
softirq to be interrupted after NET_RX processing and thus NET_RX_SOFTIRQ
to be pending again before tick_nohz_irq_exit() runs.
Dave can you:
- specify if there much traffic when the message appears
- send /proc/interrupts + ethtool -S ethX
Thanks.
