I tried to make a video of the startup process ... but it is very difficult
to get legible frames when text scrolls up very fast !!!
So ... I am posting a series of images of the startup process the best I
could get ... so ... I hope they are useful for You to tell me why my
computer keeps rebooting with a KP !!!
I appreciate all your time and help !!!

Number 4 contains the information that we need but unfortunately it is unreadable.

Do you have any non-SATA drives that you can use? DO you have a time machine backup? I had similar problems, solved them by restoring from a backup from a time machine. Btw. I found out, that the problem went away when I disabled the SATA Controller in BIOS. That is not a good solution, however, its an indication, where the problem might be. Try it.

I think I have the same problem...

Yo guys, film the boot sequence in 240fps, then you can freeze frame better again, I thing its a problem with corrupt kext files (native) and has something to do with Catalina. When I disabled the SATA controller on my motherboard in BIOS, I could boot normally, with SATA, I had the same KP. I have a NVME drive, so I'm good. What I did to repair this KP, I booted from my Catalina Install USB and reinstalled clean, then recovered from Time Machine. It seems to work now.

The same situation just happened to me after the Supplemental Update. Had to disable the SATA Controller in BIOS to be able to boot into my system. Just finishing the update and will give a report (with bootlog). I will try again to reinstall the system. But maybe there is another way (maybe restore the involved kexts?), but I’m not qualified for such advanced troubleshooting.

Hello, I'm having exactly the same problem. I cannot boot to catalina without disabling "Sata Controller".
Did you find a solution about this ?
Many Thanks

no sir, Don’t have time to experiment now, but next week I will try to reinstall with SIP enabled...nobody is helping, I guess it’s a mystery problem that only a very small group of ppl are experiencing. Let’s hope someone suggests a way to troubleshoot it
