hi everyone i have a intel atom netbook that i have arch installed on and have been using it for the last couple of years without any issues, after doing a pacman -Syu recently when i reboot it gets through boot up to the point of setting up the desktop and then crashes with  2 thirds of the screen from left to right fill with a random rows of dots on a black background and the last third has my desktop with an exit icon at the bottom, i went through the process of downgrading the kernel and got it to boot normally again i thought that because it was a 32 bit computer the problem was to do with arch no longer supporting the i686 architecture so i migrated the laptop to  Arch Linux 32, everything went smoothly , after the migration i rebooted the laptop  and i was back with the same problem. i chrooted into the laptop with a live usb stick and retrieved a portion of the journal here,s the log. error-report http://codepad.org/mtWYqv2N my Desktop Environment is lxde if more of the logs are needed please let me know i would be thankful for any pointers to fixing the problem shadrock
