Help on ext3 file system corruption issue

[Somasundaram, Arun (IE10)]

Hi Andreas,

  Thanks for your reply.

Are there any patches in this kernel for these ext3 bugs? Please guide
me to these patches if available.

What is the suitable file system for compact flash? I read that JFFS2 is
suitable for raw NAND flash card and is not suitable for CF card. Is it
true?

My application has write operation performed to the CF card even every 3
secs.(worst case)

 

Thanks,

Arun

Unless you have a support contract with some vendor, nobody will look at

bugs from such an old kernel.  There are a hundred old bugs that might

have been fixed already.

This is likely a hardware error.  Probably due to the fact that ext3

is not a good filesystem to use on CF because the journal is always

overwriting the same part of the CF device.  Try something like JFFS2

instead.
