[PCanyi]

Problem：

My system crashes and reboot suddenly and frequencely 5 time per day with error report panic(cpu 1 caller 0xffffff7f896ee9af): "[IGPU] ERROR: SafeForceWake acknowledgement never received on GLOBAL domain, fFlags.systemInSleep: 0, fFlags.enabled: 1\n"@skl/IntelAccelerator.cpp:7786

When I use vmware fusion, this problem will be reproducted quickly.

I Opened following debug options:

• [x] Debug version of OpenCore and DEBUG options with Target params args equal 67
• [x] Debug version of WhatEverGreen and DEBUG options with -wegdbg
• [x] Debug version of Lilu and DEBUG options with -liludbgall liludump=60
• [x] Kernel panic args with -v keepsyms=1 debug=0x100
• [x] set PanicNoKextDump=YES
• [x] set ApplePanic=YES
• [x] EFI Directorys with attachments

And My System and all the softwares were newest:

• Macos 10.15.5
• OpenCore 0.59
• WhatEverGreen 1.4.0
• Lilu 1.4.5

My Hardware informations are:

• Huawei Matebook x pro 2019
• Hardisk: WDC 1T
• Memory: 16GB
• DisplayCard：Intel HD4000 and NVdia Geforce
• Display : 3000 * 2000 HIDPI (Use of HIDPI script to open this)
• DVMT: Modified bios DVMT from 32MB to 64MB

I have upload all the log.

The crash report was as follows:

Sounds like a bug in IGPU drivers. A hang happens in the IGPU resulting in this kernel panic. I do not think we will investigate this, but thanks for the detailed report. Perhaps other people are interested.

Same with KBL UHD 620 on SkyLake framebuffer. 10.15.5

Laptop reboots when watching AVI films in iina player

I have also encountered this problem recently but not sure how to trigger that. Although I have ApplePanic enabled, corresponding log was not saved to EFI. From logs in /Library/Logs/DiagnosticReports/ I got some more information but stopped at IOUserClient::externalMethod(unsigned int, IOExternalMethodArguments*, IOExternalMethodDispatch*, OSObject*, void*)

I have also encountered this problem recently but not sure how to trigger that. Although I have ApplePanic enabled, corresponding log was not saved to EFI. From logs in /Library/Logs/DiagnosticReports/ I got some more information but stopped at IOUserClient::externalMethod(unsigned int, IOExternalMethodArguments*, IOExternalMethodDispatch*, OSObject*, void*)

kpdescribe.sh Fortunately I'm still on 10.15.4 and there's KDK available. I have switched to kernel.development and I'm waiting for next panic lol.

Have you found any solutions now? It was so bored when crashes had been happened.

[zhen-zen]

@PCanyi Unfortunately not yet. It's even exist on 10.16 (my first kp on Big Sur lol). I have enabled development kernel but every time it panics, it will just freeze and waiting for debugger… But my laptop doesn't have an ethernet or serial (seriously?) port and debugging through thunderbolt 3 is also not realistic. There is even no log in nvram after reboot. I tried several sets of "debug=" boot-args and trying to get it dump and reboot when it panic but none works. I'm not sure if the results will be the same as keepsyms with release kernel.

WTF, I can not hear more worse news than it If this kernel panic would also be happened at big sur. It is so bored and the system had been crashing continiously

Have you tried this? Close power nap. https://discussions.apple.com/thread/250876794?page=7

[PCanyi]

May be you are right. When I closed power nap of preferences and Use hardware acceleration of chrome and edge, it have not had any crashes from then on.

@vit9696 can you reopen this issue ? It seems not only one case.

[vit9696]

Latest WEG fixes that issue. You either do not have the latest version of loaded WEG or it is not functioning properly. Please update everything to the latest DEBUG versions and attach OpenCore (Target 67) and Lilu log (generated ondisk with liludump=60 -liludbgall in /var/log/Lilu???.txt).

[jim3ma]

@vit9696 After update to the latest WEG and OpenCore, my hackintosh run a week without panic, but it panics with another error yesterday.

你的解决了吗 @ourfor

@ourfor Did you resolve this issue? (translation by @PMheart)

[jim3ma]

@ThxGodNovember 我的是 UHD 630，更换驱动到 Intel HD Graphics CFL CRB，就没有 panic 过了，看上去之前仿冒的驱动引起的

@ThxGodNovember I have UHD 630. After changing the primary driver to Intel HD Graphics CFL CRB the panic seemed gone. Looks like it was caused by the previous spoofing. (translation by @PMheart)

Just change GPU driver to an appropriate one, nothing others changes.
