Comment 39 for bug 1514233

Greetings!

I had another freeze today at 09:00

So I am running now on 3.19.0-32-generic.

$ grub-install --version
grub-install (GRUB) 2.02~beta2-29

grep submenu /boot/grub/grub.cfg
grep gnulinux /boot/grub/grub.cfg

edit
/etc/defualts/grub
'Advanced options for Ubuntu>Ubuntu, with Linux 3.19.0-32-generic' (for versions before 2.00)
