Didn't work 

Feb 15 05:47:15 ibm/hotkey LEN0268:00 00000080 00006032
Feb 15 05:48:10 button/lid LID close
Feb 15 05:48:36 battery PNP0C0A:00 00000080 00000001
Feb 15 05:48:36 ibm/hotkey LEN0268:00 00000080 00006032

Do you think it might be that ibm/hotkey getting triggered simultaneously with the battery event and that might be what's causing this?

Hey guys!

Super stoked to get Devuan "unstable" running almost perfectly out of the box on a new ThinkPad z13.  Really fantastic work!  One of the only remaining issues is with ACPI and waking.  It has an issue where suspend wakes from non-critical battery events.  I used acpi_listen to see that:

battery PNP0C0A:00 00000080 00000001

wakes it from suspend, both when I plug in AC and when I disconnect AC.

When I try to get a 'handle' for this device:

cat /sys/bus/acpi/devices/PNP0C0A:00/path gives \_SB_.PCI0.LPC0.EC0_.BAT0

But my /proc/acpi/wakeup does not contain anything having to do with the battery, of this device:

Device  S-state   Status   Sysfs node
GPP0      S4    *disabled
GPP1      S4    *enabled   pci:0000:00:01.2
GPP2      S0    *disabled
GPP5      S4    *disabled
GPP7      S4    *disabled

HS03      S4    *disabled  no-bus:usb3-port3
                *disabled  usb:3-3
                *disabled  usb:3-3:1.0
XHC2      S4    *disabled  pci:0000:64:00.0
NHI0      S3    *enabled   pci:0000:64:00.5
XHC3      S3    *disabled  pci:0000:64:00.3
NHI1      S3    *enabled   pci:0000:64:00.6
XHC4      S3    *disabled  pci:0000:64:00.4
LID       S4    *enabled   platform:PNP0C0D:00
SLPB      S3    *enabled   platform:PNP0C0E:00

You can see that I tried disabling wakeups from XHCy, to see if that was somehow the issue, but it wasn't.  (Battery looks like its its own thing, so I didn't think it would work).  I also tried 

echo "disabled" > /sys/bus/acpi/devices/PNP0C0A:00/power/wakeup

but that didn't work either.  Any ideas?
