Hi there,
I also have this warning. It seems to occur only when mounting or remounting an
ext4 partition using the auto_da_alloc ext4 mount option. Without this option,
the warning doesn't occur. I'm using x86_64 Debian testing with a 2.6.31.6
kernel compiled from vanilla kernel.org sources running an a Samsung R560
laptop. This is what I see in the syslog:
