9070 XT LG OLED65C9 FRL training failed

[dorogush]

Using Certified Ultra High Speed HDMI cable to connect AMD Radeon RX 9070 XT directly into LG OLED65C9.

With the stock 6.19.3-3-cachyos kernel I'm getting 3840x2160 60hz 4:4:4 8bit BT2020 HDR10.

With this patch hdmi_frl_stable 17d577b applied I'm getting no signal. I tried power cycling the tv.
dmesg-frl.log

Thank you for your great work. Will appreciate any help.

Probably a duplicate of #23

I tried 435360c. Still no signal. However the logs are different. Now it infinitely loops
