dmesg output pp_num_states
Testing upstream kernel (4.17.0-rc2-ga27fc14219f2) because of the newly
introduced "wattman" functionality. On my CIK hardware (Hawaii/R9 290X), none
of the sysfs and hwmon entries work. Writing to sysfs files like pp_sclk_od,
pp_od_clk_voltage works (no error) but the hardware/driver does not react to
the changes. Reading sysfs/hwmon files like power1_cap_max, pp_table,
pp_od_clk_voltage print no output. Trying to read from pp_num_states even
segfaults (attached is the dmesg output of the corresponding error).</pre>
