I've never been able to wake up my Orange PI 5 Plus from suspend. It just goes into oblivion - requiring a hard restart. The keyboard and mouse don't wake it up. Tapping the power button doesn't wake it up. I've tried it on Armbian as well as pure Debian Trixie. Apparently something is off in the design of the SBC.
 
But also hibernation doesn't work (again in Armbian and in pure Trixie). Using a 32 GB (32 * 1024^3) swap for a "32 GB" (actually around 31 GB) RAM device, and setting RESUME to the swap partition, the hibernation option appears. But when used, it just goes into oblivion (like suspend). I left it alone like that once for about 20 minutes, it was still in limbo.  and when I (have to) hard restart it, the previous supposedly-hibernated state is gone.
 
Given that the SBC is capable of doing a power shutdown from the OS (i.e. after dumping allocated RAM to the swap), there is no legitimate reason for hibernation to not work. But it doesn't.
 
 
 

I don't have IR device to test. While in kernel driver code there is pm_ops defined: https://github.com/armbian/linux-rockchip/blob/rk-6.1-rkr5.1/drivers/input/remotectl/rockchip_pwm_remotectl.c#L1063-L1066
