<< Solved >> [Help] 10.14.4 UHD 620 random panic, AppleIntelKBLGraphicsFramebuffer

[cowcowpod]

Solved - reinstalled MacOS 10.14.3, restored from backup, updated to 10.14.4. It was probably an issue with a corrupted driver or kext..

Hi!
My hack panics in later boot stages, or randomly afterwards if it boots properly. I've tried spoofing to Skylake but it's pretty much the same.
According to panic log, com.apple.driver.AppleIntelKBLGraphicsFramebuffer is causing the crash, but I have no clue why.

I've tried not spoofing UHD620 to HD620/30, but it appears that's only for UHD630; as a result CFLGraphicsFramebuffer DOES load, but I don't have brightness control and everything generally speaking looks broken..

My config is based off of Rehabman's 615_620_630, with 1659 instead of 1b59 ig-platform-id.

ASUS Vivobook X411U
i7-8550U, UHD 620 @ 1920x1080
Mojave 10.14.4
DVMT-prealloc 64MB

Any help appreciated, dying from the random kernel panics here

Hi, I encounter same issues as yours on my Lenovo Flex5 1570 (i7-8550u, 16GB, HP-EX920-1TB, UHD620+MX130, 4K-Touch-Screen). In my situation, I tried 591B0000, 59160000, 3E9B0009, 3EA50004, only -v can boot, but 50% chance get same issue as yours. I did lot of work to get everything work perfect [Audio, Brightness Adjust (F11, F12)-Works only 591B & 5916, Touch Pad & Touch Screen Gestures (Cursor sometimes jump), WiFi & Bluetooth (DW1830), Battery.....]. But only -v can boot, & 50% chance get same issue as yours. If I remove -v, 10.14.4 boot 2 or 3 second & reboot. Hope RehabMan can fix this problem!

BTW, I tried UHD630 Clover Patch "Set the number of active lanes to 4 (for laptop with 4K display) (by FireWolf)" & "Set the number of active lanes to 2 (for laptop with 4K display) (by FireWolf)" for 3E9B & 3EA5, it does not help.

Back up, then erase and reinstall macOS. Don't restore from a back-up, instead set it up like you did, and see how well it runs. Fixed my issue, so I guess there's something wrong with _a_ system file..

Could you please share your config.plist? In my case it does not panic during the boot, but it does randomly when Safari is running and/or when there is video playback within or outside Safari. Also please tell me if you are able to use HDMI with audio?
