--- Comment #9 from Mark Haun (hau...@keteu.org) ---
Investigating some more today while I wait to see if there are still failures.

Here is my /proc/acpi/wakeup (after manually disabling everything):

Device  S-state   Status   Sysfs node
GPP0      S0    *disabled
GPP1      S4    *disabled
GPP2      S3    *disabled
GPP5      S0    *disabled  pci:0000:00:02.1
GPP6      S4    *disabled  pci:0000:00:02.2
GP11      S4    *disabled
SWUS      S4    *disabled
GP12      S4    *disabled  pci:0000:00:04.1
SWUS      S4    *disabled
XHC0      S3    *disabled  pci:0000:64:00.3
XHC1      S4    *disabled  pci:0000:64:00.4
XHC2      S4    *disabled  pci:0000:66:00.0
NHI0      S3    *disabled
XHC3      S3    *disabled  pci:0000:66:00.3
NHI1      S4    *disabled  pci:0000:66:00.6
XHC4      S3    *disabled  pci:0000:66:00.4
LID       S4    *disabled  platform:PNP0C0D:00
SLPB      S3    *disabled  platform:PNP0C0E:00

I see that my touchpad is on an I2C bus.  Here is the entry in /sys/bus/hid:

0018:04F3:320B.0008 ->
../../../devices/platform/AMDI0010:01/i2c-19/i2c-ELAN0688:00/0018:04F3:320B.0008

I can't tell if the controller is on the PCI bus.  Does "AMDI" stand for one of
these (lspci output):

65:00.0 Non-Essential Instrumentation [1300]: Advanced Micro Devices, Inc.
[AMD] Device 14ec
66:00.0 Non-Essential Instrumentation [1300]: Advanced Micro Devices, Inc.
[AMD] Device 14ec

If the touchpad I2C is not in /proc/acpi/wakeup, that would explain why I
[usually] am able to wake the system by vigorously wiping the touchpad.  If
there are ever any spurious interrupts, could this also explain unwanted wakes?
