[ 25.216133] mei_me 0000:00:03.0: timer: connect/disconnect timeout.
[ 25.216143] mei_me 0000:00:03.0: unexpected reset: dev_state = ENABLED

Ok, dmesg looks good from mei driver point of view. Do you have network slowdown (or other problems that manifests with 3.8) with this kernel?
The resetting message as you have in log usually means that is some is wrong with FW/HW - mei driver not receiving reply in timely manner.

To debug it future, you can enable dynamic debug for mei driver :
echo -n 'module mei +lfp' > /sys/kernel/debug/dynamic_debug/control
echo -n 'module mei_me +lfp' > /sys/kernel/debug/dynamic_debug/control
and wait for next reset
