No you didn't then it seems you are hit by some bug. Have the bug happen. Kill userland processes like as you did. Try find out what's running. I would look in /proc/interrupt /proc/net/softnet_stat /proc/net/dev or maybe best to take a profile if possible or Magic SysRq to find out what's looping. Also try ifconfig down.
