transissioning to level 2 I get

   Isolating 4 dofs: X Y RZ HP
   Using filter module(s): H1:HPI-BS_ISO_X H1:HPI-BS_ISO_Y H1:HPI-BS_ISO_RZ H1:HPI-BS_ISO_HP
   Isolation level: 2
   Starting gain ramp...
Time::HiRes::sleep(-0.451209): negative time not invented yet at /opt/rtcds/userapps/release//hpi/common/scripts/HPItool2.pl line 516.
 

And then the script stops, without runing on X, Y, RZ and HP.

Additionally, I noticed that a lot of these HPI turn-on scripts don't actually move to the set target position, but instead just throw a warning, asking for a manual move.  This seems like an alignment time bomb that will get us sooner or later.
