I disabled the discrete GPU BIOS (that is the current stand) but the problem remains. Contrary to #1010683, where some people were helped by using "pm-suspend --quirk-test --quirk-s3-mode", this problem is exhibited without discrete graphics (thus ruling out problems with vgaswitcheroo). WORKAROUND: Install fglrx or fglrx-updates.
