Failed to initialise power management NVMeFix

[samcabral]

I have a KingSpec NVMe 256 working and booting with NVMeFix but -liludbgall liludump=60 reports some failures and apparently no power management has been initialized.

If you need other logs for debugging, please let me know.

Logs describe well what happens.

Your controller doesn't declare the power states needed for APST, so NvmeFIX doesn't initialize APST for that drive.

Similar situation here: #1825
I believe that the solution, at the moment, is to replace the drive.

I'd update the blacklist: dortania/bugtracker#192 (comment)

Yes, my controller does not support APST but I read somewhere that PM PCI would be used when APST is not available.

Maybe it was here:

InsanelyMac/341984-nvmefix

EDIT

Well, that seems to be it.

KingSpec NE-256 does not support APST and NVMeFix cannot enable its own power management.

Pretty much, no issue here, just a hw limitation.
