Ha ha! Yes, this was true to get sleep to work correctly, but found that my system's performance had been reduced to a crawl. And on top of that, the system would now sleep, but wouldn't wake!
I found that my Cpu0Ist and SaSsdt both had huge errors and once I patched those, performance is back as it should be but wake is still an issue. I tried darkwake=0, which wakes to a black screen, darkwake=1, which worked once up to login and gave me a system I couldn't do anything with and darkwake=2, which panics on wake. I did notice in the kernel log that
[_PSS]: Namespace lookup failure, AE_ALREADY_EXISTS
but can't work out where. Also, if I
show log | fgrep "[powerd:sleepWake]"
it returns with
vm.darkwake_mode: 0 -> 0
Failed to get sleep type. rc:0xe00002c7
Don't know if that's any help? Below is my send me. Thanks.
