Is it possible to suspend the ASUS ProArt X870E with amdgpu.pcie_p2p active?

A user running llama.cpp in tensor split-mode on an ASUS ProArt X870E motherboard with two AMD R9700 GPUs reports that system suspend hangs instead of entering sleep mode, requiring a power cycle, even when no AI workload is active. The user states suspend works normally when llama.cpp does not use tensor mode, or when tensor mode is used with amdgpu.pcie_p2p=n, and asks whether suspending with p2p active is possible.

I’m using the ProArt X870E with two AMD R9700. If I try to suspend the system when llama.cpp is running with tensor split-mode it will crash. It never enters sleep mode, it just hangs, and I have to power cycle the system. By llama.cpp running I mean the system is idle with application running, it’s not doing any AI workload when I suspend. Suspend works normally as long as llama.ccp doesn’t use tensor mode, or when using tensor mode with amgpu.pcie p2p=n. Would it be possible to get the system to suspend with p2p active?
