boot - iwlwifi 0000:01:00.0: Unsupported splx structure - Ask Ubuntu

i have installed 16.04 in dual boot windows. installation ok, , couple of times ubuntu booted smoothly. now, after having chosen ubuntu @ booting, black screen appears following:

/dev/sda8: clean 271789/1222992 files, 1952109/4882432 blocks

[ 10.015870] tom_crb msft0101:00: can't request region resource [mem 0xfed40080-0xfed40fff]

[ 10.507758] iwlwifi 0000:01:00.0: unsupported splx structure

welcome emergency mode!

i tried search bit on web, there nothing specific, less clear solutions. suggestions please?

edit: here pastebin dmesg log.

also, outputs of sudo blkid

there multiple problems need answered question.

the first , foremost problem /etc/fstab. it's been radically changed standard, , windows partition trying mounted @ 2 different mount points @ same time. caused computer not boot, , halt in emergency mode. here comment out both windows disk mounts, , got computer boot.

in /etc/fstab:

---

change this:

 # /windows on /dev/sda3 during installation uuid=5cce72f7ce72c8b2 /windows        ntfs    defaults,umask=007,gid=46 0       0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none            swap    sw              0       0 uuid=5cce72f7ce72c8b2 /media/data  ntfs-3g  defaults,windows_names,locale=it_it.utf-8  0 0 uuid=2605-3dc2  /boot/efi   vfat    defaults    0   1 

to (just comment out 2 lines):

 # /windows on /dev/sda3 during installation # uuid=5cce72f7ce72c8b2 /windows        ntfs    defaults,umask=007,gid=46 0       0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none            swap    sw              0       0 # uuid=5cce72f7ce72c8b2 /media/data  ntfs-3g  defaults,windows_names,locale=it_it.utf-8  0 0 uuid=2605-3dc2  /boot/efi   vfat    defaults    0   1 

then reboot. success!

---

then, clean rest of messy fstab, following edits.

change this:

 # /boot/efi on /dev/sda1 during installation #uuid=2605-3dc2  /boot/efi       vfat    umask=0077      0       1 

to this:

 # /boot/efi on /dev/sda1 during installation uuid=2605-3dc2  /boot/efi       vfat    defaults      0       1 

then delete last line of fstab looks like:

uuid=2605-3dc2  /boot/efi       vfat    defaults      0       1 

---

lastly, change this:

 # /windows on /dev/sda3 during installation # uuid=5cce72f7ce72c8b2 /windows        ntfs    defaults,umask=007,gid=46 0       0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none            swap    sw              0       0 # uuid=5cce72f7ce72c8b2 /media/data  ntfs-3g  defaults,windows_names,locale=it_it.utf-8  0 0 

to this:

 # /windows on /dev/sda3 during installation # can't have 2 mounts, 2 different mount points, @ same time. # both of these mounts wrong. # uuid=5cce72f7ce72c8b2 /windows        ntfs    defaults,umask=007,gid=46 0       0 # uuid=5cce72f7ce72c8b2 /media/data  ntfs-3g  defaults,windows_names,locale=it_it.utf-8  0 0 # if must mount windows partition, i'd recommend this... # uuid=5cce72f7ce72c8b2 /media/data  ntfs-3g  defaults  0 0  # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none            swap    sw              0       0

then, in windows, these:

if dual-boot windows , ubuntu, must turn off fast start , hibernation in windows.

1. turn off fast start in power control panel

in power control panel, click on change power button does

then choose change options unavailable

uncheck fast start

2. in administrative command prompt window, type powercfg /h off
