[vdr] Large amount of logging with vdr on Fedora 24

I have just updated the OS of my TT s2-6400 based vdr box from Fedora 16 to Fedora 24 Server and all is working fine except the log (both journald and rsyslog) fill up rapidly with the following type of entry.

[ 1983.410546] demux_worker (0): dma buffer = 0 [ 1983.427146] demux_worker (0): dma buffer = 1 [ 1983.444525] demux_worker (0): dma buffer = 2 [ 1983.461113] demux_worker (0): dma buffer = 3 [ 1983.477710] demux_worker (0): dma buffer = 4 [ 1983.494305] demux_worker (0): dma buffer = 5 [ 1983.509629] stv090x_read_status: Status: Unlocked (Searching ..) [ 1983.511662] demux_worker (0): dma buffer = 6 [ 1983.528265] demux_worker (0): dma buffer = 7 [ 1983.544857] demux_worker (0): dma buffer = 0 [ 1983.562229] demux_worker (0): dma buffer = 1 [ 1983.578835] demux_worker (0): dma buffer = 2

I am using a custom kernel with a fork of the DVB drivers, as opposed to the stock versions of both on the Fedora 16 install, so am just wondering if anyone is running a standard late Fedora install and seeing this behaviour?

Thanks,

Richard
