For TBS5980 the only problem we have so far is this:
CI crashes when the receiver is rebooted with TBS 5980 plugged in and powered on!
More specifically:
1. These are the drivers we currently use
https://patchwork.linuxtv.org/patch/23244/
https://patchwork.linuxtv.org/patch/23243/
https://patchwork.linuxtv.org/patch/23242/
+ mis/pls patch
+ snr patch
+ ts sync patch
And here's the crash after STB reboot. Please note that if the STB shuts down and gets off power instead of rebooting, or if the card gets off power and then the STB reboots, the problem does not occur!
Here's a detailed log with the problem!

Everything else works as expected, the only problem so far is during STB reboot!
Is there anyone familiar with a reboot issue as well? What do you suggest!
