Please see other topic on same problem and try if also with your setup SoapySDRUtil --probe show same error and Python SoapySDR test program crash Ubuntu.

After this we need to test a fresh Ubuntu 16.04, not an upgraded system from 15.10

Hi, I tried with 1.95.3; unfortunately same kernel panic when using input rate of >=10000000 (no decimation) - I'm using latest gr-osmosdr with nonfree option (to support SDRPlay) and latest gqrx.

The Linux kernel developers might be interested in this. If SDRPlay doesn't use a kernel module (does it install one? I haven't found any) then there's some regression somewhere, or the parameters exposed by SDR driver might be incompatible with changes to the USB subsystem on Ubuntu 16.10.

It's 64-bit Linux, upgraded from 15.10; 'uname -a':

Linux 4.4.0-28-generic #47-Ubuntu SMP Fri Jun 24 10:09:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I'll try recompiling '/usr/local/lib/SoapySDR/modules/libsdrPlaySupport.so' this evening and see what happens; however, this is very strange indeed - it's the first consistent kernel panic I've seen in Linux for years!
