I've opened a bug on https://bugs.freedesktop.org/show_bug.cgi?id=104235 and attach a dmesg log which shows the Linux does go into sleep while booting with "nomodeset". I will try drm-tip then and update the ticket if anything interesting Chris. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
