            Bug ID: 187561
           Summary: Kernel Dump on Write-Access to when Kernel is compiled
                    without Reiserfs-Extended-Attributes-Option
           Product: File System
           Version: 2.5
    Kernel Version: 4.4.31
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ReiserFS
          Assignee: reiserfs-devel@vger.kernel.org
          Reporter: felix.wiedenroth@gmx.de
        Regression: No

When a custom-kernel is compiled with Reiserfs-Support and the Option "Reiserfs
Extended Attibutes is NOT chosen, the Kernel Crashes on Write-Access to the
Reiserfs-Filesystem. This happens when a Reiserfs is created with default
options using mkfs.reiserfs.

I observed this behaviour with Kernel-Versions 4.4.28 to 4.4.31. 

Works fine if extended-attributes are activated in the Kernel.

Problems is probably, that Kernel does not set / return default Values for the
Extended-Reiserfs-Attributes when option "Extended-Attributes" for Reiserfs is
not compiled in.

Regards,

Felix Wiedenroth

--- Comment #1 from Felix Wiedenroth <felix.wiedenroth@gmx.de> ---
When Kernel Dumps on Write-Access, this leads to a inconsistent File-System.
This can only be fixed by the reiserfs-fsck when the option --fix-fixable is
used and the filesystem is not mounted at all. 

Therefore you have to boot from CD or boot from another HDD when Root-Partition
is affected.
