RIL problems

Hello again,
I'm trying to build cm 13.0 for kanas (core 2, SM-G355H) using this source as a reference.

First of all thank you if you decide to read this.

How do you make the ril work without failing? The ril works on dual sim but later on, the phone will reboot. From the last_kmsg file, it is hinted that modemd is responsible:

<0>[   76.533472]  [2:         modemd:  241] 
<0>[   76.533541]  [2:         modemd:  241] [c2] sc8830_machine_restart (h, (null))

Then I tried compiling modemd from source that does not reboot (like the one I'm using) or trigger a kernel panic (like the one from stock). I got these messages from main buffer of logcat.

Also I'm curious about these two lines in build.prop/system.prop (which I copied from stock):

persist.sys.sprd.modemreset=0
persist.sys.sprd.wcnreset=1

No Idea what it is or what it does.

P.S.
I tried getting the dmesg log but it is always spammed by PM, cpufreq_scx35, "BUG: using smp_processor_id() in preem", and register dumps.
I think I was wrong about RILJ being the culprit but right now I have a weird feeling that it's the NVRAM's fault.

WITH_DEXPREOPT set to true, system_server crashes with SEGV_MAPERR

In cm 14.1, setting WITH_DEXPREOPT to true, would create odex files. The device would then boot up normally. After a short while the system_server process crashes causing a soft reboot. It goes on and on.

Coincidentally. I found a thread in xda. Which is, I'm amazed though, the exact error message I'm having:

pid: 13389, tid: 14235, name: Thread-11  >>> system_server <<<
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x78

And the same symptoms and trigger too.

Any insights? Sorry for the delay, I was supposed to post this issue this weeks before testing a possible fix.
