Hi!
There is a laptop:
HP Probook 4740s CPU: i7-3632QM RAM: 16 Gb Graphics: Intel HD4000, 1600 x 900 Audio: IDT 92HD87B2/4 SDD: ADATA SU800 256 Gb Ext. monitor (HDMI): Philips 223V, 1920x1080
OpenCore 0.5.7 with last driver and kext.

Installing Big Sur (masked as macbookpro11.1) from the installation flash drive.
It takes a very long time to install. Over 7 hours.
After installing it takes about 20 mins to boot and is very slow working.
The same situation when installing from the internet via the recovery.

Remove ssd from laptop and connect it via external usb.
Install to external drive.
Installation takes about 1.5 hours.
Booting in 1 minute.
Everything works: graphics, sound, network, hdmi. Quick and stable. No problems.

Putting the ssd back in the notebook.
Booting 20 min, works very slowly. Same as after installing to internal disk.

In the boot log:
Couldn't alloc class "AppleIntelPchSeriesAHCI"

I think the problem is in the SATA driver Big Sur.
Here is what Dortania writes:
Certain SATA controllers droppedFor some reason, Apple removed the AppleIntelPchSeriesAHCI class from AppleAHCIPort.kext. Due to the outright removal of the class, trying to spoof to another ID (generally done by SATA-unsupported.kext) can fail for many and create instability for others.A partial fix is to inject Catalina's version with any conflicting symbols being patched. We recommend setting the MinKernel value to 20.0.0 for the kext CtlnaAHCIPort.kext to avoid any potential conflicts.


The install this kext didn't help.
The problem remains.

Any idea how to fix it?
