On 03/15/2011 07:10 PM, Somebody in the thread at some point said:
the pandaboard does not use the VUSIM or VAUX1 power regulators on the TWL6030
and are left floating. if the VUSIM and VAUX1 power regulators are initilized,
noise on the unloaded regulators generates an overcurrent interrupt causing the
system to power down. this patch removes the initialization of the unused power
regulators of VUSIM and VAUX1.
