Motorola Defy+ :: Regularly Restarts If Data Is Turned On?

my Defy+ does also reboot. Let me explain what i already tryed.i am a T-Mobile Germany user and have a data plan called Web`n`walk flat wich only allows for webtraffic eg ports 80/443 basically.- I got the Handset replaced 2 times, however the handsets i got where not new they where "repaired" whatever that means. So i did not send mine and had to wait, actualy they replaced it at my door. So 3 different handset where the last one is the worst one. Anyway -> no difference.

- Under my contract i do have 2 SIM cards and i ask them to replace the older one with a new one so i tested 3 different SIM cards where the last once where n3 and n4 -> no difference

- delivered 2gb SD card, Samsung class2 8Gb, new Samsung 16 Gb class10, formated the 16Gb in the handset -> no difference

- 2.3.4 and 2.3.6 which i got some time at the second handset as OTA Update -> no difference

- 2 different MOTOBlur accounts -> no difference

- factory reset/cache wipe -> no difference Even i experience the reboots strait after the factory reset within the start wizzard eg on the Screen where you turn on Data Usage.

- turn data connection to 2G only -> no difference

But now:

- if i turn off DataUsage keep the phone connection active and just stay on WiFi -> no reloads for hours/days?

As the last handset keeped restarting at my house as well i connected it to the adb and capture some kernel logs.... the system dies with Kernel Panic and restarts.Here we go with an example. It is just the panic lines and a bit above. I dont understand that mutch of linux kernel debugging however. I required i could do more logs. (only without root as the phone is on the 2.3.6 kernel ROM)
