Comment # 14 on bug 1055641 from Franck Bui

Olli,

Can you try to boot with the following options added to the kernel command
line:

 "plymouth.enable=0 printk.devkmsg=on"

Once you've finised booting, enter the following command:

 # mkdir -p /run/initramfs/etc/cmdline.d
 # echo "rd.debug rd.break=pre-shutdown rd.break=shutdown" >
/run/initramfs/etc/cmdline.d/debug.conf
 # touch /run/initramfs/.need_shutdown
 # systemd-analyze set-log-level debug

And then reboot with "reboot"

If a debug shell pops up, could you show the content of "dmesg", at least the
last parts ?

Thanks.
