HDD Disk stop/start during reboot Sonoma 14.4 and newer, including 14.5 beta

[verdazil]

Hi!

My very similar build:

MB: Gigabyte Z490 VISION G (BIOS F22)
CPU: Intel® Core™ i5-10600, 3.3-4.8 GHz
Memory: Corsair Vengeance LPX 32 Gb (4 x 8 Gb) 2800 MHz DDR4
Video: Sapphire Nitro+ Radeon RX 590 (8Gb) + Intel UHD 630
Monitor: BENQ-BL2711U + LG TV 42LF650V
SSD: NVMe M.2 PCIe 4.0 Netac, 1.0 Tb
SSD: Kingston A400 SSD, 240.1 Gb + Transcend SSD220 SSD, 240.1 Gb + Samsung SSD 870 EVO 250.1 Gb
HDD: WDC WD20PURZ-85AKKY0 2.0 Tb X 2
WiFi+Bluetooth: Fenvi FV-T919 BCM94360CD (Apple Broadcom BCM4360 WMA + BCM2046B1) (OCLP for Sonoma)
macOS version: Sonoma 14.3.1

Problems and solutions

1. I was only able to get working LAN and WiFi by setting Kernel --> Quirks ---> DisableIoMapper = YES

2. Starting from version Sonoma macOS 14.4, if I restart the computer, the power to the HDD hard drives is turns off. Then, during the BIOS POST, power is turned on to the disks and they spin up one by one. This means longer reboot time, increased disk wear, and simply incorrect behavior. I couldn't solve this problem, so I'm staying with the version Sonoma macOS 14.3.1.

Hi. I haven't been using this system in quite some time. As far as the disk issues are concerned, you could try disabling NVMeFixuf.kext and see if this changes anything

Unfortunately, this does not change the behavior of the system...
