Are you have any news for my problem?

On startup system output messages:
[0.296646] ACPI BIOS Error (bug): Could not resolve symbol [_SB.PCI0.I2C1.TPL1], AE_NOT_FOUND (20210730/dswload2-162)
[0.296659] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20210730/psobject-220)

Why is the support team silent? As can be seen from other forum topics, this problem has affected many users who choose Linux OS. The problem is not quite correct BIOS DSDT table. Need BIOS update.

Error in header theme, corebook X i5-8259U

Chuwi client support sucks. And the only answer user can get from them is “linux is not supported” which is pretty lame considering that it just need a DSDT table fix…

Yeah, so i asked for BIOS update and they said they dont have one. But I saw on yt on one of review unit there is new version of BIOS
I have
2.20.1271 and this yt has 2.20.1275.
Battery under Linux works just fine on 2.20.1275 but Chuwi says they dont have that version…what a joke.
