Hi,
I got the following crash since a couple of time since upgrading one machine to
-current as of today. It seems to occurs during somewhat heavier diskaccess.
Sorry no detailed backtrace for now because I deleted my kernel.debug since the
last crash and dumping 256MB takes a long time...
Does the crash trigger anything.
