nouvea PRAMIN flush timeout

Again some problem with my old Acer notebook. System (Debian 7) hanged during the boot with message like this: “[7.284197] [drm] nouvea 0000:02:00.0 PRAMIN flush timeout”.

The solution was to add nouveau.modeset=0 to the grub.

For permanent effect:

# nano /etc/default/grub

Change line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0"

Then do:

# update-grub

And finally reboot.
