Good Morning,
Here is the backtrace that you requested. The first part is where I
mounted the block device for cachefs use. Not exactly sure why it wouldnt
support barriers. It's a u320 36.7gig is there a problem using scsi as the
block device for cachefs? Please let me if any other informaton would be
usefull.
Jacob L.
CacheFS: Found uninitialised cache

CacheFS: The blockdev does not support barriers, so the journal may not be
reliable
