On my MPC8548 based board, sometimes kernel printed out the following
messages, I wonder if it indicates the system is not normal?

pdflush used greatest stack depth: 4048 bytes left
pdflush used greatest stack depth: 4028 bytes left
pdflush used greatest stack depth: 3964 bytes left
pdflush used greatest stack depth: 3916 bytes left
