    _______________________________________________________

Details:

While activationg the SPI subsystem by setting the SPE bit in the SPCR
register the error message above is created. 

Erroranalysis:
This happens while the method HWSpi::SetSpcr calls 
core->AddToCycleList(this); if the SPE bit changes from 0 to 1.

It looks like an error in the constructor HWMegaSpi::HWMegaSpi.  The
constructor HWSpi::HWSpi is identical to HWMegaSpi::HWMegaSpi. The
HWSpi::HWSpi does not call core->AddToCycleList(this);. There this call is
commented out! An Off-list request to Klaus is pending.
