Bluetooth issue with DW1830(BCM20703A1)

[kevin335200]

Sometimes bluetooth will be automatically turned off and cannot be turned on unless reboot. (see image)
If I reboot, the laptop will say "System Variable has Changed. press F1 to enter Setup"
Unless I set Bluetooth to "Disabled" in BIOS i cannot continue the boot process.
Of course I can set Bluetooth back to "Enabled" after a successful boot, and it works again. But it's very annoying.
It happens only when using Hackintosh.

(It doesn't occur while creating problem reporting files. I will reupload ioreg when it happens again.)

"Problem Reporting" files are incomplete (you forgot to press F4, so ACPI/origin files are very old).
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the tool mentioned in the FAQ, that way it is less likely you'll omit something.

Note: You didn't patch ACPI according to the guide:
https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

Use AutoMerge=true, DropOem=false, no SortedOrder, and only add files to ACPI/patched that need patches not covered by config.plist/ACPI/DSDT/Patches.
See guide for good starter plists:

Also...
Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

Yeah.. i need to do all things again. Not only because of exist problems but also modded BIOS.
I know every time i would lack something or do something wrong, hope this time i can get all things right. Never read again and again...
I have just modded the bios for hidden opinions and now i can set DVMT-prealloc to 64MB or 128MB. which one is better?
Now i'm repatching SSDTs, i don't want to change DVMT after it in case of repatching again.
Thanks

128mb DVMT gives you more options (in case an ig-platform-id you want to use assumes 128mb, or you want to patch an existing ig-platform-id to use more DVMT).

If you use ACPI hotpatch, then you don't need to repatch ACPI whenever you change BIOS options/hardware/etc...
