Issue 1 sounds similar to the problem I had with 9500GT card and nvidia
driver. The system would lock up completed when it resumes. The only
indication that it actually resumed, is the monitor powers up,
displaying the last image after resuming. It turned out all the drivers
after 275.43 would cause my system to freeze when DVI power was sent to
the monitor. Resuming or powering the monitor on/off would lock up my
system. I have since switched to the open nouveau driver since 275 no
longer works on the 3.2 kernel.

Check your driver. If you are using the nvidia driver, you may have to
play around with different versions to find one that works. If none
works, try nouveau.
