Ken,
You could set the module parameter preallocate_big_buffers=1 when
you insmod the au8028 kernel module. When this parameter is set, the
driver will allocate the big buffers once when the module is loaded
instead of every time the device is opened for streaming.
Thanks,
Tim

Added command line parameter preallocate_big_buffers so that the digital
transfer buffers can be allocated when the driver is registered. They
do not have to be allocated every time a feed is started.

same frequency and modulation mode, the demodulator
will be reset. The au0282 drives uses this feature when it attempts
to restart the feed.
