Hi,
Since the adaption of Reiser4 for VFS my system has become less stable.
The filesystems get corrupted, files lost. e.g./etc/passwd recently, :(
, kernel Oopses and NULL pointer dereferences in the kernel. I converted
the Reiser4 partitions to ext4, and the system has become stable.
Mount options were pretty straightforward, with noatime, and no
encryption nor compression.
Unfortunately I have no time to play around with debugging, so I'll
stick to ext4 for the moment.
The NULL pointer dereference traces look like this:

Hello!
Not sure if this helps any further, but I get such NULL pointer

activated reiser4 debugging for a better crash report, or do you already
know where to look at?
