Blue Screen after flashing Tegra B-PX2, after rebooting | need help

Autonomous Vehicles DRIVE PX 2 General
1

We are getting Blue screen after flashing Tegra B-PX2. Cannot log-in or perform any activity.

After re-flashing Tegra-B, it worked for a few hours, but now the TEGRA-B is giving Blue screen and some times flicker.
Tegra-A is working fine (not re-flashed).

Need urgent help.

Some more details:

  • We (me and RatheeshR) can operate the Tegra via minicom normally, but we get this recurring message when accessing the Tegra via minicom

    (repeat)
  • After rebooting via minicom, we can again see the login screen, but the blue screen occurs right after login.
  • after changing our /etc/apt/sources.list, then running sudo dpkg --configure -a, the recurring message went away and we were able to login normally. we recommend running, after this,
    sudo apt-get upgrade -f
    sudo apt-get autoremove
    sudo apt-get upgrade
    sudo reboot

Via minicom, we replaced the file /etc/apt/sources.list with these contents:
