That's fine - those shouldn't be configured as wakeup events. > Its perfectly OK to miss events on _forced_ suspend. No, it's not. Forced suspend may be in response to hitting a key, but it may also be in response to a 30 minute timeout expiring. If I get a WoL packet in the 0.5 of a second between userspace deciding to suspend and actually doing so, the system shouldn't suspend. -- Matthew Garrett | mj...@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
