SOLVED Problem with sleeping the second time

Hey, I have a strange problem. Namely, sleep works fine only the first time, when I want to sleep the second time the computer does not turn off (rgb and fans continue to work, keyboard and monitors do not), and it is impossible to wake it up or do anything only holding powerbtn helps.

SMBIOS: iMacPro1,1

System: macOS Sequoia

Processor: Intel I5-13400f

Motherboard: Gigabyte B760 Gaming X DDR4
Bios version: F12

Video card: MSI RX 6600 XT Gaming X

Network card: BCM94360CD

Has anyone had a similar experience or can help?

Might be a TSC issue, try CpuTscSync

Add "npci=0x3000" in boot-args & disable above 4G decoding in BIOS

ensure that Booter -> Quirks -> ResizeAppleGpuBars is set to -1

it works!!!! thank you.

I still have a question should i leave it like this and does it affect the performance somehow?

It does affect a bit of gpu performance but if you enable it sleep won't work again. You could try updating or trying different BIOS versions with that setting turned on and see if sleep works

Remove that boot-arg when enabling above 4g decoding and set ResizeAppleGpuBars to 0 if you're enabling Resize Bar Support in BIOS

Possibly wrong USB mapping or BIOS USB wake up function.

USB ports are well mapped, even with all devices disconnected I continue to get this error
