I've similar issues and believe it might be due to the amount of kernel 
printfs that are happening. Can you sysctl debug.wpi=0  and see if the 
problem still exists?
By chance are you using ZFS? I caught a memory modified after free panic 
in zfs the other day pid was from syslogd. I'm trying to work out if 
it's related.
