Bus error using rtl-sdr

Hi

I'm experiencing a "bus error" everytime rtl-sdr tries to interact with my
SDR. Here's a sample:

rtl_fm -f 1000000
Found 1 device(s):
  0:  Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM
Found Rafael Micro R820T tuner
Tuner gain set to automatic.
[R82XX] PLL not locked!
Tuned to 1252000 Hz.
Oversampling input by: 42x.
Oversampling output by: 1x.
Buffer size: 8.13ms
Exact sample rate is: 1008000.009613 Hz
Allocating 15 zero-copy buffers
Bus error


I'm running Kali on a Raspberry Pi, and I've used the repository version,
and compiled from source — no change. The only thing that makes this error
go away in `rtl_test` is to pass it the -S flag (forcing synchronous) flow.

Does anyone have any idea how to fix this?
