DVB S2: Unable to find symbol ds3000_attach()

Hi,

my system has a DVBSKY DVB-S2 TV Card (well recognized as Montage Technology DS3000); it has worked fine initially (after loading the required firmware) but has stopped working recently. I *think* it could be related to installing NVIDIA drivers, maybe.

When starting kaffeine now, I get a popup that no device with valid settings was found and that I should go to the "Configure TV" menu. No device is shown there.

The only related dmesg I can find is
[    4.705109] failing symbol_get of non-GPLONLY symbol ds3000_attach.
[    4.705111] DVB: Unable to find symbol ds3000_attach()

and maybe a related issue at the level of the 6.5 kernel opened early September:

https://lore.kernel.org/lkml/2023090708 … 97441@mir/

Indeed, I also get
dmesg | grep -i -e dvb -e dw21 -e ds3000 -e symbol
[    4.699860] cx23885: cx23885_dvb_register() allocating 1 frontend(s)
[    4.699899] cx23885: cx23885[0]: cx23885 based dvb card
[    4.705109] failing symbol_get of non-GPLONLY symbol ds3000_attach.
[    4.705111] DVB: Unable to find symbol ds3000_attach()
[    4.705114] cx23885: cx23885_dvb_register() dvb_register failed err = -22
[    4.705116] cx23885: cx23885_dev_setup() Failed to register dvb adapters on VID_B

Does anyone have the same issue?

I have never had to deal with kernel patching, so I would like to have some advice how to receive and apply a correction.

Any help appreciated, thanks!

Hello again;

I have received an answer from Greg @linuxfoundation.org, who is/was working on the bug:
"Please work with your distro to update their kernel to the latest one and all should be good."

Question: what options do I have going forward?

Should I uninstall NVIDIA, and how is this done?

Best,

T.

Re: DVB S2: Unable to find symbol ds3000_attach()

So I spoke again with Greg Kroah-Hartman who maintains the 6.1 kernels.
He says that it should be solved with kernel 6.1.54. Since Q4OS is on 6.1.52-1 at this moment, I would like to know when you will switch to 6.1.54.

Maybe this is worth moving to bug tracking?

Thank you.

T.

Q4OS just follows Debian kernel line. If you want to switch to a newer kernel, please see https://q4os.org/dqa011.html#system.6 , or follow instructions for Debian Bookworm.
