Ubuntu 4.13.0-21.24-generic 4.13.13
I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 17.04, which gave me this error after 2 weeks of usage. After that, I installed 16.04 and used it for MONTHS without any problems, until it produced the same error this week. I think it has to do with the ubuntu updates, because I did one recently and one today, just before this problem. Could be a coincidence though.
I notice the error when I try to save something on disk and it says me that the disk is in read-only mode:
lz@lz:/var/log$ touch something
touch: cannot touch 'something': Read-only file system
lz@lz:/var/log$ cat syslog

Rebooting the ubuntu will give me a black terminal where I can run fsck /dev/nvm30n1p2 (something like that) and it fill fix a lot of orphaned inodes. The majority of time it boots back to the Ubuntu working good, but some times it boots to a broken ubuntu (no images, lots of things broken). I have to reinstall ubuntu then.
Every time I reinstall my Ubuntu, I have to try lots of times until it installs without an Input/Output error. When it installs, I can use it for some hours without having the problem, but if I run the software updates, it ALWAYS crashes and enters in read-only mode, specifically in the part that is installing kernel updates.
I noticed that Ubuntu installs updates automatically when they're for security reasons. Could this be the reason my Ubuntu worked for months without the problem, but then an update was applied and it broke?
I thought that this bug was happening: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried different nvme_core.default_ps_max_latency_us= combinations, all them gave errors. I just changed to 0 and I had no error while using ubuntu (however I didn't test for a long time) but I still had the error after trying to update my ubuntu.
My Samsung 512gb SSD is:
SAMSUNG MZVLW512HMJP-00000, FW REV: CXY7501Q
on a Razer Blade Stealth.
I also asked this on ask ubuntu, without success: https://askubuntu.com/questions/998471/razer-blade-stealth-disk-corruption-fsck-needed-probably-samsung-ssd-bug-afte
Please help me, as I need this computer to work on lots of things :c
