Some more detailed context can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793 Scope (_GPE) { Method (_L13, 0, NotSerialized) { If (LEqual (PFLV, FDTP)) { Return (Zero) } Store (Zero, GPE3) Or (GL08, 0x10, GL08) Notify (\_SB.PCI0.SAT0, 0x82) Return (Zero) } } This is the DSDT code for GPE13 on a Samsung Series 7 700Z5C laptop. There error reported by the Linux kernel is: ev_queue_notify_reques: No notify handler for Notify, ignoring (SAT0, 82) Now, my question is: How do I find out what device is causing the GPE13 interrupt and why? How do I work out what code (which device register bit to reset) I have to put in this Notify handler in order to silence the interrupt storm?
