Big Sur Public Beta 2 kernel panic

[global6000]

I have been successfully running Big Sur Public Beta 1 for the last few weeks and it has been very solid and stable. Better than Catalina for me anyway. So I was confident to update to the new Public Beta 2. I read in the forums that it seemed the update went smooth as butter for everyone that tried. So I updated through system preferences. It proceeded normally until it got hung on a kernel panic on restart from the folder called Install MacOs made during the install. I then tried doing a clean install on the drive from my USB boot pen drive after downloading the full Beta 2 separately and transferring to my USB. That made no difference got the same kernel panic. I have also since tried updating Lilu to 1.4.7 as I compiled it myself. All my other kexts are the latest releases. I am on OC 0.6.0. I have attached photo of kernel panic. I apologize for the low quality of the photo.

Any assistance would be appreciated.

Also my SIP is locked. Not sure if that would cause a problem.

Did you try NVRAM reset option?

I will try that now. Just trying another clean install.

Nvram reset made no difference. Still kernel panic

I will attache the latest OpenCore boot text error record. Hopefully someone can see an issue. I see it ends with [EB|#LOG:EXITBS:START]. So I tried adding a MMIO whitelist to see if I could solve this but did not work.

As you can see by the Skip 1 I only had one active at a time and tried each one seperately but none worked.

I also attached my config if that will help

I dont see the issue here. Yes I use graphical interface so the picker mode is external and I hide auxillary so I have a cleaner screen for boot.

It says "No slide values are usable!" Maybe it's an NVRAM issue.

 

[global6000]

I have tried reseting and cleaning NVRam to no effect. Is there anything else I can try?

If no slide values are usable, NVRAM should be broken. Try adding boot argument "slide=0" to see if it helps.
