Can confirm the issue on my LG Gram 17Z90Q-K (2022 model) running Manjaro (Arch) with Kernels:
6.4.2-3 (latest version I have available on my system)
6.1.38-1 (LTS)

Happens both connected to my Thunderbolt 3 dock that also charges the computer, or to the power supply. Doesn't happen when running on battery power.

Doesn't happen on my LG gram from 2021.

1. I didn't find any reports of this issue for the 2023 models. Did anyone?

I believe that we need either a Linux Kernel patch or a BIOS update, but there doesn't seem to be any updates to the BIOS of the 2022 lined up of LG Gram.

2. How can we get this fixed? Who can save us!?

3. Are there any workarounds that can be programmatically applied?
Someone here: https://bugzilla.kernel.org/show_bug.cgi?id=217076#c7
suggests setting the kernel parameter acpi_mask_gpe=0x6E
But I'm resistant to try it because:

```
When you specify a kernel boot parameter like acpi_mask_gpe=0x6E, you're telling the kernel to ignore or mask a specific ACPI GPE, in this case, the GPE with the address 0x6E.

This can be useful in certain scenarios where a specific GPE is causing issues, like system instability or high CPU usage. By masking the GPE, you prevent the system from processing that event, which can work around the issue.

However, you should only use this parameter if you are sure that the specific GPE is causing issues and you understand the implications of masking it. In some cases, it can lead to other problems, like certain hardware events not being correctly detected by the OS.
