This is definitely a regression, but I don't think a lot of people are noticing it or don't yet have 6ghz access points. I can write up a patch removing the offending commit (698b166ed), or I can add an iwlwifi option to ignore the 6e ACPI bit. Which would you prefer? Dell has been of little help which I pretty much expected. @Luciano, as you were the author of the original change, and I'm not familiar enough with ACPI, is the below code reading the enable bits from the BIOS ACPI table or is this somehow coming out of the network card through some UEFI extensions? I'm trying to figure out which of Dell or Intel need to update their firmware? I think some Lenovo's have similar problems, so I suspect it's a BIOS ACPI table problem. ret = iwl_acpi_get_dsm_u32(mvm->fwrt.dev, 0, DSM_FUNC_ENABLE_6E, &iwl_guid, &value); Thanks, Dave.
