Hence, i can only guess, but I've fixed a locking issue in 47dffa7f5958b75a660684b64c1d58afc637daef. I'm not 100% sure it's the cause of your panic since i've still to reproduce the panic.

Thank you for your time and help, I really appreciated.

It is difficult to get a good core.txt file after the system panics. After I do a 'call dumpsys' and reboot the system the boot loader is lost and 
kernel. i try booting by loading the old loader and kernel but get I no loader, kernel found. I reinstall the OS so i could try again with the save
sources i have, but i saw after the reinstall, the core file was copied into /var/crash, I used that to upload. 

I reinstalled the OS untared my sources 3.8.0 did a git pull 
the OS still panics and a lock is getting lost.
a message i get is: panic: lockmgr LK_RELEASE: no lock held

if needed i can start the process again and type the rest of the screen message?

Best regards,
