Sorry, unfortunately I do not speak turkish. I translate too online the forum to understand it. I hope you will understand. Or try translating :).
I had some similar problem when migrating my 2.1.2 Pisilinux installation from hdd to ssd. It looks like the 4.19 kernel is not working everywhere on ssd (find info somewhere on archlinux forum). So I have tried the 5.4.19 from and 5.10.5 kernels from https://ciftlik.pisilinux.org/testrepo/pisilinux/core/master/k/kernel/ or https://ciftlik.pisilinux.org/2.0-Beta.1/k/kernel/ repo. Both worked. Now I am using the 2.1.2 Pisilinux with the 5.10.5 kernel every day without any issue. Maybe the later kernels - 5.10.11 or 15 might work too.
If when the black screen appears but pushing the CTRL+ALT+F2 the console appears, you can sign in as root and you have acces to the kernels pisi package (from repo or downloaded previously), than you can install in commandline from within pisi.
WARNING! DO not upgrade other packages than the kernel, because they will screw up 2.1.2 Pisilinux installation.
I hope this info can help.
