That's interesting. I've been seeing this message for some time now
(I think since around 2.4.15 at least, maybe longer). I modified the
printk to display the device number, and at that time, it seemed to
always originate from the partition that had a mounted HFS volume.
So I just added that to my (long) list of HFS bugs to fix when I
find enough time to dive into it.

However, I just got a report from some users having the same message
displayed when using parted and with no HFS partition (HFS filesystem
not loaded). I personally see this messages when using/leaving MacOnLinux
emulator (which is opening the block device of a partition that is also
mounted), or when shutting down the box.

Al, any clue ? Something you want me to do to track it further down ?

Ben.
