Hi Greg
6.15.5-rc1 compiles on x86_64 (Xeon E5-1620 v2, Slackware64-15.0), and boots on x86_64 (AMD Ryzen 5 7520U, Slackware64-current), no dmesg regressions observed.
However, on my machine in /etc/rc.d/rc.local there is
echo 20 > /sys/class/backlight/amdgpu_bl0/brightness
to adapt the brightness early in the boot process to save energy. It works for me with kernel 6.15.4 before /etc/rc.d/rc.local is invoked there is:
cat /sys/class/backlight/amdgpu_bl0/brightness 50
but with 6.15.5-rc1 there is something off. I get a blank screen as greeting. The network works.
Right after boot (before invoking /etc/rc.d/rc.local) I see: cat /sys/class/backlight/amdgpu_bl0/brightness 400000
A comparable level of dimming on -rc1 to kernel 6.15.4 with my tuning is with a brightness value of 100000
I noticed there's -rc2, will test soon.
