dont know if it has something to do with hardened opts in the kernel. I will try with non hardened kernel but really like to have it running with.
pointers to get it running are appreciated.
From what I can see, it's failing when setting up a DMA transfer from the usb device, not something I do directly, so may be a bug in either the rtl-sdr library, or perhaps libusb stuff?
does rtl_test -S do the same thing?
Hi...sorry for the delay.
rtl_test seems to run fine (no errors on the console).
I'm now running
# uname -a

but rtl_entropy still fails with "library error" (same as above) and also the page allocation failure.
if it helps this is the libusb version installed:

not an expert here but to me it looks like it has problems reading from the usb device. any clue?
so after looking on the trace more closely i discovered that the req. usb driver could not be loaded. after kernel recompile it looks like it works.
sorry seems to be entirely my fault.
