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?
