Note that testing kernel sometimes *requires* additional set of loader settings like kernel parameter tuning and/or set of kernel modules loaded including NICs or GEOMs like gjournal/graid that may affect boot process. And our loader does apply such settings when processing nextboot.conf. Maybe this is the reason nextboot.conf should be removed after it fired once. I personally edit it manually every time I use this feature and I keep a copy of the file with distinct name to restore it for another run.
