Your firmware is non-free, so it is packaged separately (source package
firmware-nonfree, binary package firmware-mediatek).  But it is also
included in the netinst image.

The netinst and live CD images are 2 different things.

The installer should detect these log messages, then:

1. Install the required firmware package
2. Remove and reload the driver

Is that not happening?

This sentence contradicts itself - no actually it doesn't.

For that device the PHY driver appears to be phy-mtk-pcie, which is
*not* currently included in the installer.

For the other PCIe port the PHY driver appears to be phy-mtk-tphy which
*is* included in the installer.

Can you confirm whether I am right about the PHY drivers?

Is it possible that you originally tested the WiFi/BT card in port 1,
and then tested it in port 0 this time?

I already reassigned this to the relevant installer component
(hw-detect) because I thought the only issue was failure to handle the
firmware installation.

However, the kernel package (linux) controls the selection of drivers to
be included in the installer, so a missing PHY driver is a bug there.  I
will duplicate and reassign the bug report again if necessary.

Ben.
