GPD Win Max 2 2023 - early wake from suspend

Brief summary of the problem:

My GPD Win Max 2 2023 (AMD Ryzen 7 7840U) wakes up early from suspend (s2idle).

I will leave my device overnight, unplugged, with the lid closed. In the morning I find that it's no longer in s2idle (evidenced by the solid blue light instead of slowly pulsing blue light). I also find that the battery has drained by roughly 10 or 15 percentage points.

I can repro fairly consistently using amd_s2idle.py. It seems that the device usually wakes up after about eight and a half hours. I have yet to reach the full 10 hour duration I'm attempting.

Hardware description:

The device is a GPD Win Max 2 2023 (AMD Ryzen 7 7840U), with 64GB RAM, 2TB NVME, a second 2TB NVME (in the M.2 2230 slot), WIFI, 4G LTE modem w/ SIM (but disabled / not in use). No external peripherals.

System information:

  • Distro name and Version: Fedora 39
  • Kernel version: Linux fedora 6.6.14-200.fc39.x86_64 #1 (closed) SMP PREEMPT_DYNAMIC Fri Jan 26 20:12:16 UTC 2024 x86_64 GNU/Linux

Note, I am currently using an rc.local script to disable three wake sources:

echo disabled > /sys/bus/i2c/devices/i2c-PNP0C50:00/power/wakeup
echo XHC0 > /proc/acpi/wakeup
echo XHC1 > /proc/acpi/wakeup

If i2c-PNP0C50:00 is enabled, then the device does not suspend properly. I have disabled XHC0 and XHC1 because I've observed them generating spurious wakeups in the past.

Here's the contents of /proc/acpi/wakeups:

$ cat /proc/acpi/wakeup
Device	S-state	  Status   Sysfs node
GPP1	  S4	*enabled   pci:0000:00:01.2
GPP0	  S4	*disabled

XHC3	  S3	*enabled   pci:0000:67:00.3

NHI0	  S4	*disabled
NHI1	  S3	*enabled   pci:0000:67:00.6

How to reproduce the issue:

  1. Charge laptop to near full and place on table, unplugged, no external peripherals connected.
  2. Close lid. Observe that the blue led begins to pulse slowly indicating the device has entered suspend.
  3. Walk away and wait 10 hours.
  4. Come back and see that the blue LED is solid. Open lid, see that battery has dropped by 10 or 15 percentage points.

Thanks for reading!
