Computer: HP i5 Compaq 8100 64bit.

OS: mythbuntu 16.04.

Kernel: 4.8.5-040805-generic.

Application: MythTV 0.28.

Country: Australia DVB/T2/C.



Installed the PCIe board.

Copied the firmware dvb-demod-si2168-b40-01.fw to /lib/firmware/ and
installed kernel 4.8 to get the required driver.


Your Linux Support shows the lspci output to be as follows:

I expected version (rev 04) but I got (rev 03) above and note that
Linux Support
chip PI7C9X2G304 is NOT listed below:

and have received the following one line reply:

"At this time we have only tested kernel 4.4. Have you tried the patch
attached? "


The patch is attached.


Installing the patch is well outside my understanding of Linux,  I need
explicit step by step help to achieve a change to the kernel.

Should I revert back to kernel 4.4 as the very first action?
