[Remix OS for PC] Whitest:
Ok I did some more testing and got a DMESG/Logcat from the bootloop now. I hope this helps to find the culprit. I deleted all files in /su/su.d/ except 00xposed and 00daemonsu. I also checked that the Dalvik-Cache was cleared and rebuilt.

Here you go:

Is this a normal warning?

<6>[ 18.916147] capability: warning: `daemonsu' uses 32-bit capabilities (legacy support in use)

and I guess here something starts to go wrong... first pastebin line 824

I'll also provide another DMESG of boot with the working ramdisk - because the original one still works fine...
