Since version 3.0.59, OMV enables the backport repo by default and also installs the backport kernel by default. Because my haswell system wont go in P-state C6 with the default r8169 kernel module, i've installed the r8168 module from Debian stretch manually.
Since the last version i must install the driver and the kernel headers every time manually with a new kernel version. This i quite annoying.
How to revert the changes and get the debian stable kernel by default every apt upgrade?
The debian stable kernel is also supported by debian, very important to get security updates.
