Bad block Management Patch

[-- Attachment #1: Type: text/plain, Size: 358 bytes --]

Hi Boris,


I am using kernel version-3.0.35
I am facing uncorrectable ECC error in ubifs. I am suspecting, it is because of bad blocks are not properly handled in my driver.
Is there any patches available to handle the bad block in the specified version...


Best regards

Is this a joke? Now you're not even adding the mailing list in Cc, and
you keep giving too few information (I don't even remember what's your
NAND controller).

I suggested that you test a mainline kernel, and you keep asking for
patches on top of a really old kernel. And by the way, don't expect us
to do your job (you can use git log and try to apply the patches that
seem relevant to you, but I clearly won't do that for you).

So please stop asking us to fix your bugs unless you start listening to
our suggestions, and the first one is to try a newer kernel (4.9 for
example).

Thanks,

Boris

This is not how community support works.
He happily help with recent kernels but debugging problems on
outdated kernels with vendor patches applied is out of scope.

What you expect from us is hard and takes a lot of time, we cannot
do that for free in our spare time.

Are you sure your hardware isn't breaking down?

Also, can you try the 4.9 kernel tree?  Lots of ubifs changes have
happened since 3.0 was released, over 5 years ago...

thanks,

Hi Greg,

Thank You for the information. I have few more concerns here,

I am facing the following uncorrectable ECC error, Can you suggest any kernel version or any patches to overcome this issue.

That is very very old and obsolete and insecure.  I strongly recommend you update to a modern and maintained kernel version in order to get any help from the community, and to ensure that your device actually works properly.

If you are stuck at this kernel version because it is supported by a vendor, please contact them for support as you are paying them, and they are the only ones that can help you out.

Good luck!
