E6230 Freezing following sleep after 10.15.5 update

[scram69]

Following the update to Catalina 10.15.5, my E6230 is experiencing frequent freezes (requiring holding the power button to restart).

I noticed Herve's comment for this update about the cpu-specific SSDT, but I had already generated that and put it into EFI/Clover/ACPI/Patched.

I also have the SSDT-PNLF.aml from Jake's guide in there as well - do I still need that?

I'm running Clover r5118

I've attached my debug file.

 

Thanks in advance for any advice-

You have a kinda of hybrid configuration with conflicting settings: for instance AICPUPM patch + generated CPU-specific SSDT but also KernelPm patch and no dropping of CpuPm/Cpu0Ist SSDT tables. You need to chose which CPU power management method you want to use because it's either/or, not a mix of them.

Hi Herve,

 

Thanks very much for the reply.  It's been a while since I reviewed my power management settings.

 

I realized that instead of dropping specific SSDT tables, I was setting DropOem=true, which is only recommended for SandyBridge and older CPU's.

 

But I have two follow-up questions if you wouldn't mind helping me a bit more:

1) RehabMan's "generic" HD4000 1366x768 config.plist also drops Cpu0Cst and ApCst.  What about those two?

2) I did not think I had the KernelPm patch enabled as it is both unchecked and "greyed out" in Clover Configurator. RehabMan only recommends it for Haswell and later.  But sure enough, when I open config.plist in a text editor, KernelPm is set to /true.  Is this a bug in Clover Configurator?  Should I just edit config.plist by hand and change /true to /false?

 

Thanks again-

Absolutely no need to drop those 2 x tables.

KernelPm patch is now enabled by default in Clover. If you don't use XCPM, it's irrelevant and so, does not matter.
