Garbage collection failed

Hi
  I am running timesys linux on my custom made 8250
board. The board has AMD flash with interleaving as 2
and buswidth as 32. I have created two partitions one
for ppcboot and another jffs2. At the boot up the MTD
layer successfully probes the AMD flash and
recongnises both the partitions. After the kernel
boots I copy the JFFS2 image file into /dev/mtd/1.
When I mount the JFFS2 I keep getting the following
error:

"jffs2: No clean _or_ dirty blocks to GC from! Where
are they all?\n");

After delving into the code I found out that garbage
collection is done from a kernel thread. When I
comment out that code I am able to successfully mount
JFFS2. 

Any idea why the garbage collection is failing. 

Thanks in advance

Does the mount fail, or does it just print this and continue working?

Hi David
  I am not sure. The console is flooded with the same
print message. I cannot do anything so I have to reset
the board.

I have seen this message also (on our DragonBall VZ based
board). But it appears only during shutdown/reset (when the
JFFS2 partition remains mounted and the GC thread is running).
