openmoko io error

[previdi.roberto at gmail.com]

sometimes, with no particular cause, but always when the phone is in use (using gps, or while getting the gsm signal, or while playing mokomaze), the image on the screen become corrupted by white horizontal lines, then the enlightenment crash window appears, and if i click on the second button it shows the console with this error:

... ad libitum

Then, when i reboot the phone it will not find the gsm signal for ages and for many reboots. 
Then, eventually it will work again.

is this normal? i tought it seems some electric bug related to the video chip and to the gsm chip...
