What steps did you do in between that screenshot and trying to get last_kmsg?
Waited about 3 minutes for the device to boot into TWRP
Sounds like the kernel isn't booting, just to verify, state your device again? viennaltexx right?
Correct, this is also the name of the cf autoroot tar (or SM-P905).

I just tried to grab the log again. Unfortunately, after flashing TWRP the only thing I see is still:
Are you using 2.7.0.2? You might need to try odining stock to get out of the issue with cache.
Yup, thanks, that's what I ended up doing flashing back to stock firmware, but now I can't reroot it lol it gets stuck at cache.img
Next time after that happens, just flash the stock recovery via Odin (I found I could still boot into download mode) and it will get you out the boot loop. This happened to me when wiping cash on the latest version also.
Yes but in this case it is saying that it is failing to mount the cache in recovery.
It's taking a while to do the secure cache erase. If this fails it seems to have issues. Odining stock recovery fixes it usually.
For me flashing twrp first then rooting works like a charm. Then in twrp need to enable the -rf option and that will allow clearing the cache for the time being.
Sorry I meant rm -rf option. This makes it so that it won't format partitions when wiping which can cause issues in some cases it seems. If you have an issue with cache, then odin stock image onto the tablet. When you flash TWRP back select this option so TWRP won't format your partitions.
