Here's a "me too" for resume troubles in 2.6.28, MacBook Core Duo with i915 graphics. I'm about a week behind in my git tree though. Probably unrelated, but in testing other stuff I noticed that 2.6.27.3 worked whereas 2.6.27.4 does not. Reverting "ACPI Suspend: Enable ACPI during resume if SCI_EN is not set" makes it work there. In 2.6.28-rc3, reverting the same commit met with mixed success: * resuming from X got me one successful resume after a long timeout, and one resume with mouse-pointer-only * resuming from console always worked With the above mentioned commit, resume never worked. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
