Hi Folks,
I just subscribed after having trouble with this card that worked for 3
years on Skylake i5-6500 but stopped tuning when I moved it to AMD Ryzen
5 3400G machine. I found the workaround in the archived thread
referenced in the subject line and don't know any way to reply directly
to it: https://www.spinics.net/lists/linux-media/msg114563.html
My card is ATSC as on this page:
https://www.kernel.org/doc/html/v4.10/media/v4l-drivers/cx23885-cardlist.html
57 Hauppauge WinTV-QuadHD-ATSC 0070:6a18, 0070:6b18
and
[rolf@x570i coup]$ lspcidrake -v | grep Conexant
cx23885 : Conexant Systems, Inc.|CX23887/8 PCIe Broadcast Audio
and Video Decoder with 3D Comb [MULTIMEDIA_VIDEO] (vendor:14f1
device:8880 subv:0070 subd:6b18) (rev: 04)

Neither scan, dvbscan, nor w_scan2, nor Kaffeine TV, while finding
working frequencies, could divulge any services. The workaround was in
the referenced post: cx23885.debug=8
I've seen another report of a different kernel option that worked on
Ryzen: |cx23885.dma_reset_workaround=2 here:

Ok. Just wanted to join the chorus with a *metoo* in case I can provide
some (guided) forensics.
Thanks,
Rolf
