This is probably not related. As far as I can see this issue was about
boot problem with discrete graphics while your problem is related to
suspend/resume.
The next thing I would try on your machine is to get some kernel debug
messages from resume. This might be hard to get, since your notebook
has probably no serial port. But you can try to boot with
no_console_suspend on the kernel cmdline and see if it gives you any
output on resume.
Maybe some of the VT-d guys can take a look too?
