>I've been running into a kernel panic pretty consistently when using 
>data=journal.  This occurs during heavy IO, and is highly reproducible 
>(only takes about 5 minutes of IO to cause it).  The applications being 
>used are MySQL, Postfix, and a mail filtering application which operates 
>on postfix queue files using mmaped IO.

>Shortly before the crash, the following messages are logged:
