For starters the system in question is an HP Elitebook 2530p running Freebsd 9.1 Release, and while I must state that prior to upgrading to 9.1, suspend/resume worked perfectly under 9.0 however now I can suspend/resume successfully only once after the system has been powered up, and everything connected to the system seems to come up and function properly but any subsequent suspend actions start to work and then seem to lock the system at what appears to be when it is trying to suspend any usb devices or possibly just after shutting down usb. I will happily provide any output to whomever might be interested in lending a hand, thanks again in advance.. JAson
