Do you by chance have an OLED panel? I believe what's going on is that userspace is writing zero or near zero and on OLED panels with older kernels this means non-visible.
Yes, this is an OLED panel. But I don't believe it's userspace writing anything at this point in the boot; before the bisected commit, brightness was set to 32 (out of max 255) on this hardware when I checked from the initramfs rescue shell. At the bisected commit, it's 0 (out of max 255).
There is another commit that fixes the behavior that is probably missing.
Which commit is that? It's not in 6.15.7?
https://github.com/torvalds/linux/commit/39d81457ad3417a98ac826161f9ca0e6426...
No; it's not currently backported. Assuming it helps your issue I think it's a good argument to backport.
I cherry-picked this on top of 6.15.7.
It doesn't help much; it's possible to make out that the panel is not completely back, but even in a dark room it's so dim that it's very difficult to read anything. /sys/class/backlight/amdgpu_bl1/brightness is 0 and max_brightness is 399000.
So to reiterate: before 6c56c8ec6f9762c33bd22f31d43af4194d12da53, brightness when amdgpu is loaded got set to 32/255 (about 12.5%). After, it gets set to 0.
I also added dump_stack() to amdgpu_dm_backlight_set_level as you've suggested on the issue linked from the above commit, and it shows that brightness is set to 0 in a stacktrace starting from __do_sys_init_module. So I would say it is not userspace setting it to 0. dmesg follows.

OK, I think we need to do two things to figure out what's going on.
1) Let's shift over to 6.16-rc6. Once we've got a handle on the situation there we can iron out if there are other patches missing or this is also broken for you in 6.16. If it's not working as expected there either we need it fixed there first anyway.
2) The starting brightness I don't expect to be "0". We need to see what values were read out from the firmware. There is a debugging message we can catch if you boot with drm.debug=0x106. Keep in mind you probably need to increase log_buf_len if your ring buffer is set too small too.

PS: I would rather you add logs into a gist, pastebin or a bug somewhere if you can.
