A regression seriously affecting the Linksys WRT1900ACv1 (Mamba) was
introduced some time between the OpenWrti/LEDE v4.4 and v4.9 kernels.
The root cause has not yet been identified, despite many attempts for
more than a year. However, disabling CPU_IDLE, and implicitly CPU_PM,
has been proven to be an effective workaround.
The symptoms on an affected system are unwanted reboots a a variable
frequency. In many cases almost immediately after boot, causing a
bootloop. This effectively disables support for Mamba on OpenWrt
with kernels > v4.4.
Disabling CPU_IDLE for now to reenable Mamba support.

Please try this variant instead, which should not affect unrelated devices:

It's in my staging tree at

Works for me. Thanks. Much better solution.
Confirmed fixing the reboot problem on another Mamba.
