[Help] Sleep/Wake Kernel Panic - Intel i5-6200U (Skylake) Laptop - macOS Tahoe

[josh anderson]

Hello community! I've recently been experiencing a kernel panic when putting my laptop to sleep, and it seems to happen right after using OCLP-Plus, but I'm not sure. The problem is that when I put my Mac to sleep, if I open it later, I see a black screen, and it shows no signs of life whatsoever. (I have to force-shut down the motherboard using the power button for 10 seconds.) When macOS wakes up, it gives me this log: 

 panic(cpu 0 caller 0xffffff800658f05d): thread_invoke: preemption_level 1, possible cause: blocking while holding a spinlock, or within interrupt context @sched_prim.c:3033

That's what it shows when I restart my laptop. I've attached the latest OpenCore log I have, it's from a few days ago, and my IOregistry in case that helps. I'm considering using your new tool I saw today, DMI DECODE HARDWARE; it's worth trying: 

OP LOG AND IOREGISTRY.zip

If someone could help me identify the problem, I would really appreciate it. I'm used to going to sleep with my laptop asleep so that the next day I can simply open the lid and continue from where I left off. Lately, it happens every time I put my laptop to sleep, not every two days like it used to.
 Thanks!! <3

Seems the problem is PS2Controller

Some wrong bootargs for ur build too

[josh anderson]

Thanks for the quick reply, MaLd0n!

Regarding PS2Controller: I am currently using the latest Acidanthera release (v2.3.8). Do you recommend switching to an older/specific version, or is there an ACPI patch/SSDT fix I should apply to prevent it from blocking powerd during sleep?

Regarding the boot-args: These are the ones I currently have: alcid=13 -igfxdvmt -igfxsklaskbl brcmfx-driver=2 -amfipassbeta revpatch=sbvmm

(Note: I am using -igfxsklaskbl to spoof my HD 520 Skylake graphics as Kaby Lake since Tahoe dropped native Skylake support).

Which specific boot-args should I remove or change to clean up my config for this build?

Thank you so much for your guidance!

Progress: I stopped using only voodoops2 because my PC uses an I2C HID mouse, so I installed the voodooRMI and voodooi2c kexts. Now it sleeps properly and the trackpad quality has improved dramatically, but the system takes up to 8 minutes to boot, which is incredibly slow. Is there anything I can do? In verbose mode, it often gets stuck on something like "Iokit daemon stall (60): "pxsx". Please help, Mald0n!

Thanks!! <3
