If too many\nillegal packets arrives, tun_do_read will keep dumping packet contents.\nWhen console is enabled, it will costs much more cpu time to dump\npacket and soft lockup will be detected.\n\nnet_ratelimit mechanism can be used to limit the dumping rate.\n\nPID: 33036 TASK: ffff949da6f20000 CPU: 23 COMMAND: \"vhost-32980\"\n #0 [fffffe00003fce50] crash_nmi_callback at
