This moment when right before the holidays your @starlabssystems #Starlite V suddenly stops seeing any Wifi or bluetooth because the last #Debian #Bookworm update now requires iwlwifi firmware version -77 to -89 but the stable firmware-iwlwifi package provides -72, and you need to switch it to backports to get -77, only you have no Wifi or BT... (of course I have an USB Wifi dongle *and* an USB-C to USB A adapter precisely for these cases)
@aaribaud @starlabssystems Did you file a bug against the relevant packages for this issue? Without a bug, things don't get fixed and others will run into the same problem that you did.
I don't expect cross compatibility when mixing stable and backport between kernel and firmware packages.
I'll look into the issue of not booting after a coreboot upgrade, though, because BIOS and kernel versions ought to work whatever the combination.
