My ASUS PU551LD laptop has a problem with its fan state when resuming from S3. In particular, the fan goes to full speed a second or two after waking up and cannot be reset without turning off the laptop. For example, rebooting to Windows and doing a suspend/resume cycle while the fan is in bad state will not reset it. I have observed this behavior with all kernel versions I have used on this laptop (oldest being 3.16, newest 4.1-rc5). sensors(1) does not show any fans, but asus-nb-wmi exposes /sys/class/hwmon/hwmon2/pwm1, which shows values like 85 during normal operation but goes to the expected 255 when the fan is running at full speed after waking up from S3. acpidump output: https://0x0.st/9Z.out Not being a kernel dev (but knowing C), what can I do to help fix this issue? -- 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
