Just 3 suggestions:
1. Again, tried 6.2.1 or 6.3? Trouble may have to do with the kernel version in 6.2. Also, other live distros running without problems?
2. Checked for BIOS upgrades for the computer model?
3. Tried booting with GRUB? When you are able to swap drives, you could try with a drive with GRUB installed.

Because the kernel seems to panic so early, I'm not sure you can get so much useful information from it. I always find it much easier to start from something working that from something that doesn't.
