Kernel task > 100 is unusual and likely the problem, explore further
Activity Monitor/All Processes, Hierarchically is more useful
AppleIntelInfo is helpful before and after sleep
Okey I've literally spent hours and hours searching for the answer.
In the end I came to the conclusion that:
- The high CPU load after sleep does not occur on my old fashioned spin-harddrive. If I carbon copy the entire image to my SSD, somehow it starts again. On a side note I've read that the Samsung SSD (840 in my case) is notorious for causing problems on a hackint0sh. As a precaution I updated the firmware.
- After I followed this advice:
Resolved!
Even with PM fixed, I continued to have high CPU after wake due to kernel_task. I was able to fix it by disabling the following items in BIOS - don't know which one fixed it - will have to try process of elimination to figure that out:
Changed XHCI from Smart Auto to Auto
Disabled VT-D - I used to have it disabled, but having it enabled didn't have an impact so had left it as default.
Disabled Wake On Lan - Even though this is disabled under Energy Saver, I disabled it in the BIOS.
Disabled Thunderbolt.
Not sure how to mark this post as resolved. - If I enable trim for my SSD, if I try to put it to sleep, it just wakes up 1 second later.
- I have to use darkwake=10 for my setup.
Once again thanks for all the hard works guys, I really appreciate it!
