[Galaxy Note 3 Android Development] ShermanLiu:
Maybe A Bug Of VPN Module?

Bootloader:N9008ZMUGOH2

ROM Version:V8.2

(I've tried to fill in the bug reporting form in page 1, but it's so damn hard for people live in China to get on google website because of the censorship, so I have to post it right here, sorry if I'm doing something wrong.)

First of all, let me say thank you to all developers of this rom, your work is amazing, the rom is running fast and smooth like butter!

I'm using your HLTE V8.2 ROM on my N9008 (Which is the chinese Galaxy Note3 version), it's working fine most of the time, but recently I've noticed a strange problem, when I try connecting to a VPN (no matter PPTP/L2TP/IPSEC), sometimes my phone will just stop responding and reboot (paused for about twenty seconds then straight to black screen and bootloader logo), when I go and checked the 'last_kmsg' file, at the end of it shows something like this:

I really don't know what to do right now, I've tried full wipe, change SIM card, even changed my micro SD card, but nothing works.

I couldn't help but noticed there's a line which shows

[ 1195.727498]I[2: VpnService: 5379] WARNING: at /home/android/temasek/13.0/kernel/samsung/hlte/kernel/softirq.c:163 local_bh_enable_ip+0x4c/0xc4()

,is there something wrong with this file? Or is there something wrong with my phone?

Really looking forward to your reply, please help!
