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.
Cheers.
