Could be motherboard drivers.
Right now, the consensus seems to be that folks with my situation to stay away from SP-2.
Many of the other glitches are being addressed and repaired. The maker of this laptop, "Averatec" and AMD appear to be clueless right now, because "opteron" servers are also being affected.
I am still waiting for word from the technical people at Averatec, but I am not holding my breath after reading some of the commentary on this.
If they need to re-write the drivers to accommodate SP-2, I understand why they are not amused.
