E7270 reboots on wake when docked or removed from dock

I am using Jake Lo's OpenCore 0.6.3 EFI for my E7270, plus the ssdt.aml that I generated for this machine and added to /EFI/OC/ACPI as SSDT-PM.aml.

Whenever I dock or remove the laptop from the dock, it reboots, with the following "System Sleep Wake Problem Report":

Sleep Wake failure in EFI

Failure code:: 0xffffffff 0x0000001f

This issue only started with open core 0.6.3.  I've attached my EFI folder.

Has anyone else had problems with E7270 and the dock?

An update - 

I did the Hackintool/USBInjectAll.kext thing to generate a new USBPorts.kext as well as the SSDT-UIAC.aml and SSDT-EC-USBX.aml.

I removed what you had and installed those into OC/Kexts and config.plist.  Unfortunately, that didn't help.

 

However, I found others with the same "sleep wake failure" issue fixed the problem by disabling the serial port in the BIOS.  This seems to be working for my E6430 as well.

Hope this helps anyone else who runs into this issue-
