[Ubuntu ] -- Linux kernel 4.10.0-30-generic -- Airspy module crash !

[souldreamfr]

Hello,

Seems something is broken on last Ubuntu :

Linux 4.10.0-30-generic #34-Ubuntu SMP Mon Jul 31 19:38:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Once device is plugged i have a module crash over Airspy.

I do a complete delete of media / staging/media & recompiled all modules, but after a reboot , i have the same error / crash.

I use the kernel installed by default on last ubuntu , but i installed media driver ( DVB ) from luis to get TBS card opensource working.

As the driver is backported to an older kernel, it doesn't offer
enough quality for its usage in production.
Use it with care.

Any advice ?

I recompiled new kernel vanilla ( last up to date ).

So seems the integration of media driver ( DVB ) is the source of the crash !

You can close the ticket :-)
