TP-Link CC2600: Crashlog not active

Hi folks,

I'm running a self-built snapshot of OpenWRT (r10307-629e6538a1) on my CC2600.
Crashlog is enabled via my config. However, I still get the message that crashlog did not allocate any memory: "[ 0.048799] No memory allocated for crashlog".
Is this a (configuration/Setup) bug?
Is it not possible at all due to hardware restrictions?


Does it work with a an official build from
