[7.7.] Other information that might be relevant to the problem

       (please look in /proc and include all information that you
       think to be relevant):

[X.] Other notes, patches, fixes, workarounds:
I have not found any workaround. I have tried booting on latest
"www.sysresccd.org" in order to try on a later Kernel version. But the
error is the same. It seems like some files on my filesystem are
corrupt and trigger this when being read.

I have run fsck on my system and also from the sysresccd (v 1.42). No
errors are being reported.

I can run "mv" on a broken file if that is of any help to you, ls
shows file size.

Best regards,

Frej Eriksson

Your file system is corrupted, and there are two bugs.  (1) e2fsck
wasn't detecting this form of file system corruption (a zero-length
extent entry), and (2) the kernel was not noticing until an assertion
check using BUG_ON, instead of flagging this as a file systme error.

The fixes for both of these problems, in the kernel and in e2fsprogs,
are here:

Hi,

Thank you for your the information! If i get you correct does it mean
that you need to have an updated version of both the kernel and
e2fsprogs in order to have the issue fixed? Or is it enough to run
e2fsprogs with the patch applied?

Best regards,
Frej Eriksson

If you run e2fsprogs with the patch applied, it will fix the file
system corruption that caused your kernel to BUG.  If the file system
corruption happens again (for whatever reason; kernel bug, hardware
problem, etc.) then the kernel will BUG instead of printing an
"EXT4-fs error" message and marking the file system as corrupted.

If you have your file system set to "tune2fs -e panic" there will be
no difference (since after the error message the kernel will be forced
to reboot so e2fsck can fix the problem).  But if you have your file
system set to "tune2fs -e continue" or "tune2fs -c read-only", where
you prefer that the file system be mounted read-only or just simply
continue after noting a file system corruption problem, and you want
that behavior, then you'd have to apply the kernel patch as well.
(You can see what the corrent behaviour on file systems errors by
looking at the output of "dumpe2fs -h /dev/sdXX | grep ^Errors".)

Regards,

						- Ted
