Description Felix Wiedenroth 2016-11-13 22:03:54 UTC 
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 Felix Wiedenroth 2016-11-14 10:57:30 UTC 
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.
