Synopsis: kernel{thread taskq} uses 100% CPU

State-Changed-From-To: open->closed
State-Changed-By: marcel
State-Changed-When: Sun Dec 8 03:29:43 UTC 2013
State-Changed-Why: 
The problem was caused by the DIAGNOSTICS kernel option. The kernel
option does add significant overhead and is best not to be used in
"production" environments without good reason.
