--- Comment #1 from Andrew Morton <[email protected]> 2010-06-04 23:36:46 --- Well, it's complaining that the underlying device's driver didn't call the secret, undocumented bdi_register().
Please describe the stack which underlies that ext3 filesystem so we can go hunt down the offending code.

--- Comment #4 from Larry Finger <[email protected]> 2010-06-05 03:13:49 --- I do not think openSUSE 11.3 M7 uses a loop on boot. The dmesg output indicates that device-mapper was initialized 17 secs before the WARNING; however, I'm not using it. I will blacklist the DM modules and see if I still get the WARNING.
The demesg output just prior to the WARNING is

--- Comment #7 from Andrew Morton <[email protected]> 2010-06-05 04:23:22 --- Well that's not much use - that's just the default value and all it tells us is that nobody called bdi_register(). Bah.
That add_disk() fails to check the bdi_register_dev() return value doesn't help.
Blah, over to you Jens!

--- Comment #8 from Larry Finger <[email protected]> 2010-06-05 14:54:58 --- I'm willing to work on this, but don't know where to start.
Is there a simple explanation of when and where bdi_register() should be called?
I put a test of the returned value of bdi_register_dev() in add_disk(), but never got a non-zero result.
BTW, is this snippet in bdi_register() correct?
if (bdi->dev) /* The driver needs to use separate queues per device */
goto exit;This smells like an error, but returns zero.
