SLR? SLP? what's that?

Hi, I'm running debian 2.2 with kernel 2.4.2 with APM installed. It works fine if I suspend it and bring it back afterwards. But today after I unsuspended it, pppd wouldn't start up, and printed something like 'SLP safety enabled' or something similar, maybe SLR. But what's this safety enabled
