TBS6508 DVB-C si2183 6-0067: read_status fe0 cmd_exec failed=-5

[EgidijusL]

Use TBS6508 with DVB-C on Cesbo Astra. Now all msi is off (grub, modprobe.d) and same problem.
Random time, random tunners show "FE_READ_STATUS failed [Input/output error]". Only restarting the server helps.

Hi. I installed Ubuntu on the server on April 20, 2002 and for a week now there have been no problems with TBS.
Kernel version: 5.4.0-73-generic

[EgidijusL]

Ubuntu, 5.4.0-89-generic
The problem is still .. several days after system reboot. These errors spin and then the system stops (freeze):

We have the same issue, then after a reboot, seems half of the tuner died completely:

Adapters 0-3 on the tuner work, adapters 4-7 are dead and will fail registering.
