Title:
Sudden Read Only File System
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello.
I've got a critical problem with my computer, and i don't know why.
The file system suddenly becomes read-only.
All application (chrome, firefox and idea) that i use turn off and i can't
even reboot. This trouble happens 3, 4 or 5 times a day (from 9 am to 18 pm)
Ubuntu 16.04 LTS is installed.
Kernel : 4.8.0-52-generic
My Hard drive has been changed and i still got this trouble.
My hard drive is an SSD. My partition is /dev/nvmeOn1
Here is the dmesg output after I got the error :
