Description Michael Zapf 2023-09-12 21:08:46 UTC

Since upgrading to 6.5.2, I lost support for my DVBSky DVB-S2 card:

$ dmesg
[...]
[  219.154089] SMI PCIe driver 0000:07:00.0: card detected: DVBSky S950 V3
[  219.262797] dvbdev: DVB: registering new adapter (SMI_DVB)

[  219.264487] DVB: Unable to find symbol m88ds3103_attach()

VLC and kaffeine accordingly report that the card cannot be found.


Previously, with 6.4.11:

$ dmesg
[...]

As for DVB-S, I already got used to do a snapper rollback when there is a minor release number switch.

Most probably this[1] will fix it.

Comment 2 Stakanov Schufter 2023-09-14 07:19:35 UTC

I confirm this with a system running a dvb-s card Montage Technology M88RS6000 based Hauppauge card. 

The symptoms were already present way before only intermittently. Kaffeine states: 
Card not connected

When trying to open a channel, it gives: "no suitable card found or access permissions are erroneous"

So no error message, but apparently the card it finds is not the right one (montage) but the DVB-T one (silicon) 
The card is mentioned here:

Hello Ivan.
with which kernel version will this fix be integrated in the kernel, do you happen to know? Just to know when we have to look for the outcome and report back. Thank you.

It's in 6.5.3 which is heading to factory soon.

You can check with Kernel:stable in the meantime.

I confirm that the update:
6.5.3-1-default #1 SMP PREEMPT_DYNAMIC
restores functionality. 

Thank you for fixing lightning fast, outstanding!
