[BULK] - Re: unexpected dirty buffer

[Phil White]

Nicolas,

Is this partition mounted with data=journal?  I get the same errors 
consistently whenever I use data=journal.  In my case, it seems to be a 
bug with certain data access patterns (I have an application that makes 
heavy use of mmap'ed IO and can trigger these errors once a minute, 
followed by a kernel panic not long thereafter).  Until this bug is 
fixed, I am using data=ordered (the default), which produces zero errors.
