Bootlop during early boot with hardened 5.1.1 on leo

[lsfxz]

When flashing exposed (86 or 75, with installer or with TWRP) on Sony Z3 with jaguar leo lp 5.1.1, the boot process hangs during early boot, ie. before device decryption.

Unfortunately that's why I was not able to get a logcat: It seems to occur before adbd starts, so adb just keeps "waiting for device".
I've tried adb and LiveBoot (which neither stores any persistent logs nor displays them during startup) to get logs, and I was also not successful with modyfing boot.img to include an early logcat service in init.rc. There's also no last_kmsg available.

The developer of the ROM suggested it might be caused by one of the security patches from October [see: here and here

It also occurs when the device is not encrypted, by the way.
Flashing the xposed uninstall zip makes it boot again.

Is there any other way to get some kind of log data or anything else I could try to help to understand the issue / maybe even fix it?

Could you try it with Xposed's own logging? https://github.com/rovo89/XposedBridge/wiki/Bugs#how-can-i-get-logs

I tried that: This comes up emtpy as well.
