Hi, the mcp251xfd driver uses a threaded irq handler to queue skbs with the can_rx_offload_* helpers. I get the following error on every packet until the rate limit kicks in:
NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!! Adding local_bh_disable/local_bh_enable around the can_rx_offload_* calls gets rid of the error, but is that the correct way to fix this? Internally the can_rx_offload code uses spin_lock_irqsave to safely manipulate its queue. Best regards, Daniel
