[Pkg-samba-maint] Bug#806314: samba: OSMC Client has problems using samba with kernel 3.16, but not with kernel 3.2

[Jochen Pawletta]

Package: samba
Version: 2:4.1.17+dfsg-2
Severity: normal

Hello

I have a little problem with my OSMC Client on my Raspberry Pi.
I watch mkv-files which are shared by samba on my Debian 8 server.
The files are 1280x720 H264, nothing special.

My server is on jessie a longer while now, but due to boot problems
I was still on kernel 3.2 ...
Everything works fine as it should.

Recently the boot problems are solved and I am now on kernel 3.16.
Now I have problems watching the same MKV files on my Raspberry Pi.
Often the picture freezes and it takes a few seconds (1-5) before
the video continues. It looks like the data didn't come quickly
enough for a continuous playback.
Also skipping forward takes a little while, much longer as before.

I tried to switch to the old 3.2 kernel, and that does the trick.
The problems went away without any other changes.

On a side note - I also had problems with netatalk 2.2 (debian package).
There the solution was to mount the ext3 filesystem with option "noacl".
So also this smaba-problem could have something to do with the way
a filesystem is mounted?

This is the output of mount:

kernel 3.2, it works:
/dev/mapper/RAIDvg-Sambalv on /var/local/samba type ext3 (rw,relatime,errors=continue,barrier=1,data=ordered)

kernel 3.16, does not work:
/dev/mapper/RAIDvg-Sambalv on /var/local/samba type ext3 (rw,relatime,stripe=384,data=ordered)

Could you give me a guess what went wrong here?
