Surface Pro 9 Business: Suspend/wake up with lid does not work properly

[Lucrtz]

Hi,

I'm using a Surface Pro 9 Business with freshly installed Arch Linux and the linux-surface Kernel set up according to the instructions. So far everything works perfectly, except for the problem that the device only goes into suspend mode once after a reboot when I close the lid. It never wakes up from suspend mode when I open the lid. After it goes into suspend mode once by closing the lid, it doesn't work again.

I also tried messing around with the logind.conf under /etc/systemd/logind.conf by commenting out

HandleLidSwitch=suspend
HandleLidSwitchExternalPower=suspend

which had no effect.

When I investigated the dmesg output, I found the following problem, which led me here:

[    3.868851] surface_gpe: no compatible Microsoft Surface device found, exiting
[    3.990270] surface_serial_hub serial0-0: SAM firmware version: 6.101.139
[   24.600041] surface_serial_hub serial0-0: event: unhandled event (rqid: 0x02, tc: 0x02, tid: 0x01, cid: 0x1a, iid: 0x01)

[  102.812272] surface_serial_hub serial0-0: rx: parser: invalid start of frame, skipping

Then i looked in the surface_gpe.c file and found one entry for the normal Surface Pro 9 which searches for the following SKU number:
DMI_EXACT_MATCH(DMI_PRODUCT_SKU, "Surface_Pro_9_2038")

My sudo dmidecode -t system output is:

# dmidecode 3.5

SMBIOS 3.3.0 present.

Does the problem occur because of a missing entry for the Business model of the Surface Pro 9 in surface_gpe.c?

Expected behaviour
Surface goes to suspend and wakes up from suspend when closing/opening the lid.

Does it wake via the power button?

Likely. But there have been some reports that resuming from suspend crashes when it's done by opening the lid, up to the point of people removing/blacklisting surface-gpe (linux-surface/linux-surface#1183). We can add the entry but I'm not sure whether it will fix the overall problem.

Yes, waking up via the power button works fine, even after the one time it went to sleep by closing the lid. Ok yeah i read about that. I will try adding the entry locally and rebuild the module. I hope the GPE number under lid_device_props_152 is the same as with the normal Pro 9.

Ok, so I cloned the repo, added the entry and installed the module. The device was now recognized, but I ran into the same problem, it went into standby mode every time the lid was closed, but it didn't wake up with either the power button or the lid.
