Warning during GC, resulting in to Magic Bitmask Error for JFFS2.

[Niraj Maheshwari]

Hi,

I am using Linux 2.6.10 kernel and  mounting the JFFS2 partition from
Intel NOR flash after booting the system. These error doesn't appear
always, it only comes
if we follow the steps explained below.

1. Boot the system and mount the JFFS2 partition. It happens without
any error at the first time.
2. Copy enough data to JFFS2 mounted directory so it becomes full.
3. Once the mounted partition is full, we delete few files from the partition.
    We get following warning when we do that.
    "jffs2_reserve_space(): Low on dirty space to GC, but it's a
deletion. Allowing.."
4. Now again reboot the system now we get below errors while mounting the 
   JFFS2 partition.

  jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at
0x0013cad4: 0xa6fc   instead
  jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at
0x0013cad8: 0x6e03 instead

stead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013caec: 0x5aec in

It would be really great if you can help me out to fix this problem. 
Pl. note that i am only using the JFFS2 support which has come along
with the 2.6.10 Kernel.

Pl. help me out to fix this problem.

Thanks
