I have a Asus R556L, running Ubuntu 18.04LTS on dual boot with Windows 10. The sata mode in the bios is AHCI.
Ubuntu works fine, but after working for a while, it goes to the black terminal screen with these errors, very similar to this post. Windows works for some seconds and then I have a blue screen error and the PC reboots.
When I get this black screen the computer doesn't respond anymore and I have to reboot with the power button.
After reboot, I got the log files from the two previous boots with
journalctl -o short-precise -k journalctl -o short-precise -k -b -1
There is one error that might be interesting (no usb device is plugged):
Cabirto kernel: usb 1-6: device descriptor read/64, error -110
And also some of the kind:
Cabirto kernel: print_req_error: I/O error, dev sda, sector 922702400
I booted from a live CD to make some fix with the hard drive unmounted:
I tried to run
sudo e2fsck -p /dev/sda5
/dev/sda5: clean, 785130/39829504 files, 54124587/159286528 blocks
(translated from French)
I ran a quick smart test
smartctl -t short /dev/sda and
smartctl -l selftest /dev/sda which gives
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed without error 00% 3418
An extended smart test found no error.
fdisk -l shows (with loop devices removed):

EDIT : until this morning Windows worked fine but now I have a blue screen error and the PC reboots.
Edit : when modifying the grub menu as suggested in the comments, the message in the black screen changes and there 'ata' lines appear.
