 I upgraded to NCS V1.6.0 and there were several errors 
 So when I compile now I get several KCONFIG errors and it fails.

&lt;p&gt;&amp;nbsp;It seems like these was removed by &lt;a href="https://github.com/nrfconnect/sdk-zephyr/commit/6483e12a8ac4f495b28279a6b84014f633b0d374"&gt;this PR:&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;It seems like most of the samples just comments these out (and adds&amp;nbsp;&lt;span&gt;CONFIG_BT_BUF_ACL_RX_SIZE&lt;/span&gt;)&lt;/p&gt;

&lt;p&gt;It seems like this Kconfig was removed when &lt;a href="https://github.com/nrfconnect/sdk-zephyr/commit/99cbee3f16d286f21780ca85142af95311035a4d"&gt;moving subsys/power to subsys/pm&lt;/a&gt;:&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;a href="https://github.com/nrfconnect/sdk-zephyr/commit/86a624e2a2793111f7099c31cb473d1617e5ee1e"&gt;https://github.com/nrfconnect/sdk-zephyr/commit/86a624e2a2793111f7099c31cb473d1617e5ee1e&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I think you can just remove this Kconfig, like the sample &lt;a href="https://github.com/nrfconnect/sdk-zephyr/commit/86a624e2a2793111f7099c31cb473d1617e5ee1e#diff-935eaebd7b515bccee3be125480ae17947e07523e137236cb6e30db2079adee3L3"&gt;zephyr/samples/boards/nrf/system_off/prj.conf&lt;/a&gt;&amp;nbsp;did.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
