Post your EFI Might need to patch the pre-allocated DVMT, see here Dell don't have the option in the BIOS to set it conveniently like HP

currently I'm running Monterey, with no problems, on my precision 5510. but more on that in a second. I just got a 5530 yesterday, and spent the day trying to install macos on it. but, it kept getting stuck just trying to boot into the installer. kernel panics kept happening. IONVMEFamily.kext is where it was failing. after doing some research, there are 2 models of ssds that are having issues with that kext. the Samsung PM981, and the micron 2200s. looking into the drives that came on both my laptops, the 5530 came with the micron ssd, and looking back at what drive came in my 5510, i found out it originally had the Samsung one. obviously the samsung drive is not currently in my 5510. and I have a replacement ssd on order for my 5530. Hopefully that fixes my problem. just sharing my experience to point out something to check if your having NVME errors, as it seems from my experience, the trouble drives were shipped on these laptops. https://dortania.github.io/OpenCore-Install-Guide/macos-limits.html#storage-support otherwise for troubleshooting purposes, if you think it might be related to the wireless card, disable the related kexts in your config.plist, and see if the errors resolve themselves.

Hi @Lorys89 yes! force polling work too, but I think force polling will take more resource, so I decide to try activate touchpad with Interrupt mode.

I was asked if the above trick was deprecated because DVMT pre-alloc can be bypassed with some Whatevergreen patches but sometimes it's still needed. For example, you want support for 4k display, DVMT will need to be increased and the bypass won't work. It's not recommended for everyone since it can brick your system if done incorrectly. But you can still reset it back to default by setting the BIOS to load the default or remove all the batteries for a period of time.
