hello
i have problem after updaed to kernel 6.5, the screen goes black (doesn't
display anything), after entering password in login screen
but after i revert back to kernel 6.4 or 6.1LTS, booting is OK, no problem

here is my hardware specs : (output from inxi -Fazy)
https://0x0.st/HWrO.txt

here is output of journalctl at booting with 6.5
https://0x0.st/HOnf.txt

and here is output of journalctl at booting with 6.4 (for comparison)
https://0x0.st/HOnm.txt

i have reported this at manjaro forum :
https://forum.manjaro.org/t/kernel-6-5-doesnt-work-with-amd-a9-apu/148383/13

laptop works fine with kernel 6.4 / 6.1LTS, just i am curious why 6.5 doesn't
work (& based on my personal interpretation from journalctl output, it may
related with KDE...)

any help is deeply appreciated
