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

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:
https://www.dslreports.com/forum/r32639318-SFF-3400G-build#32640298
Ok. Just wanted to join the chorus with a *metoo* in case I can provide
some (guided) forensics.
So there is a commit for a related issue:
https://git.linuxtv.org/media_tree.git/commit/?id=4bd46aa0353e022c2401a258e93b107880a66533
That is kernel v5.0 and higher. So:
1. What kernel are you using?
2. What is the full lspci -n of your machine?
Thanks,
Sean
