I haven't experienced this issue before, but judging by the log I'd guess between either the firmware it's trying to load is corrupted or the firmware on the nfc chip is corrupted, hopefully it's the former.I'm having an issue where I can't enable NFC on my phone, I've tried to look for the solution to this but I can't seem to find a solution, I am wondering if I have done something wrong or just missing the plain obvious. NFC worked on the stock ROM so I don't think its a hardware issue.
When the phone is turned on the NFC option is unticked, if I try to tick it it just greys out.
To troubleshoot I'd suggest a full wipe and a clean flash of a stock rom. You could try a clean flash of a custom first if you like, then the stock rom if that doesn't work.
And in terms of camera and battery performance, I haven't noticed a significant difference between this and stock.
