copy problem with mtd partition

[Manoj]

Hi,

I have two mtd partitons on a NAND flash and one of them keeps the
jffs2 filesystem. I can mount the jffs2 fs, read and write files off
of the mounted directory. But when I  copy a big file (11 MB) to any
location in the mounted directory, the call never returns. The
partition is 112MB big. Sometimes, a small file copy can produce the
problem.

I enabled jffs2 debugging and I see this in dmesg:

[  167.250000] jffs2_erase_pending_blocks completed
[  167.250000] jffs2_reserve_space: ret is -11

[  167.250000] jffs2_erase_pending_blocks completed
[  167.250000] jffs2_reserve_space: ret is -11

It seems like jffs2 can't find a block to write to? What could be wrong?
