Kernel Panic on Second Sleep on Sonoma 14.5 - Suspected IONetworkingFamily (with AppleIGC 1.5)

[RGAO002]

Hi all,

I've been experiencing a recurring issue where my Hackintosh fails to sleep a second time after a successful first sleep. The system panics with the following error, even after updating to AppleIGC.kext v1.5 which mentioned a fix for a related kernel panic #12.

A peek for the kernel panic information:
panic(cpu 0 caller 0xffffff801d5944ae): Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IONetworkingFamily. Thread 0x1b0f3d.
Failure code:: 0x00004000 00000014

Below I have attached a full KP log just for the record.

Has anyone faced a similar issue or can provide any insights on how to resolve this? Any help would be greatly appreciated!

Thanks in advance!

Can confirm. Seems like a different issue though, though I'm not entirely sure.

I might have encountered a similar problem. In the latest 15.1 (24B83) system, I'm unable to put my computer to sleep or shut it down properly. Instead, the system will restart automatically. Have you solved the problem you encountered? If so, could you please give me some guidance?

Hi,

Based on the kernel panic logs from @RGAO002 , I discovered that the issue might be caused by the network card’s RX buffer memory being swapped to the disk. However, the hard drive was already in sleep mode, leading to a timeout and triggering the kernel’s watchdog. I have made some modifications to address this. Could you please test and let me know if the problem still occurs?

Thank you!
