Hauppauge pci card failure. Drm coming into play?

[Galaxysurfer]

I have two servers running as DVRs

Server #1 is on Debian based PC with Hauppauge pci cards

Server #2 is on Win 10 with HDHR tuner

tonights scheduled events failed to record on Server #1

All the shows sent error message
Recording missed due to capture device failure.
This was for shows on 2 different tuner instances.
All the errors happened exactly on the hour ( the beginning of scheduled recording time) so I differentiate that from antenna signal issue as root cause. OR maybe it is indeed a signal issue? I dont have option for a different antenna now to rule that out completely.

Server # 2 all scheduled shows recorded without issue.

When I did a dmesg lookup on server #1. I had many errors regarding nouveau drivers. So is this verification that drm is blocking my recording on Server #1? or do I need to get other firmware & device driver versions?
I would have to make a new computer instance with Ubuntu to gather the drivers. I dont want to go to all the trouble if it wont fix my issue.
I know my quad card had an update recently from updating software on win 10 dual boot side. I dont use the win 10 side as dvr for other complicated reasons. I only mention it for troubleshooting purposes.

What are others here experiencing?

I am in Canada on atsc 1.0 standard OTA.
