Bug#597226: severity: Grave
I tested without the nvidia driver and the problem continues to happen.
I did 3 tests:
1 - With Nvidia driver installed and using nvidia driver
2 - With Nvidia driver installed but using nv driver instead of nvidia
3 - With nvidia drver uninstalled and using nv driver. The lsmod does not show nvidia modules loaded.
In all tests, when I rebooted the system (I rebooted the system 13 times), no error occured, but when I shut down the computer and after turn it on, the problem occurs in 70% of times, more os less.
I tried to reboot the system and shut down the computer before the grub show up, but doing this, the problem occurs in next boot.
Do you have more suggestions?
