I'm getting below results by just stopping the syslog daemon and setting printk log level to 9: [root@qemu ~]# service syslog stop [root@qemu ~]# echo 9 > /proc/sys/kernel/printk With this the printk messages goes to the console, allowing us to see the dccp_pr_debug messages till the very moment when a soft lockup happens at dccp_ackvec_parse. [root@qemu ~]# modprobe dccp dccp_debug=1 [root@qemu ~]# echo 3 > /proc/sys/net/dccp/default/rx_ccid [root@qemu ~]# echo 3 > /proc/sys/net/dccp/default/tx_ccid Oh well, not reproducing it right now, try with these settings to see you reproduce it in your setup.
