Orin NX HDMI kernel panic when shutdown and connect Dell monitor

Hi all

We use custom board with HDMI and Orin NX 16GB on Jetpack 5.1.2

Modify pinmux table and Device Tree add os_gpio_hotplug_a = <&tegra_main_gpio TEGRA234_MAIN_GPIO(M,0) GPIO_ACTIVE_LOW>; on display@13800000.

and add r35.4.1 release note chapter “4.2.3. AdaptationtotheCarrierBoardwithHDMIfor theOrinNX/NanoModules”

HDMI hotplug can operate normally, but the same Kernel panic message may occur when shutting down, making it impossible to shut down.

The only workaround currently is to modify 0x2212000 before shutting down?

Best Regards
Jack Lan
