I have the Framework 13 with Ryzen AI 9 HX 370 w/ Radeon 890M. I’m having an issue on any kernel after 6.15 where I get a black screen instead of the disk encryption password prompt (i.e. kernel 6.16 and 6.17 at the time of writing do not boot). This is similar to what is described here: Framework Laptop 16 (AMD Ryzen 7040 Series) - #6 by pubesos
Workaround has been to interrupt GRUB during boot and select the Qubes option with the 6.15 kernel and occasionally test the later kernels as they get updated.
