The cramfs image is in flash, mounted as root via mtd blockdevice.
Typically the error occurs during flash reprogramming (

using mtd char

device '/dev/mtd0' ) ...during/after flash programming the cramfs
filesystem 'loses' information ( files disappear ).  The

errors from syslog

are 'error during decompression', typically the error

numbers ( from

'linux/zlib_fs.h' ) are Z_BUF_ERROR, for the first error,

and Z_DATA_ERROR

for the rest.

Ummm... can you please explain EXACTLY what you
are doing? You have a
cramfs in flash, mounted as root, and you are erasing and

overwriting

the SAME cramfs partition WHILE RUNNING FROM IT?

No, I have redundant cramfs images in flash.  I am erasing
and overwriting the
inactive image while the other, active image,  is mounted as root.
