Hi hariprasad. nvme-core.default_ps_max_latency_us=1500 and ASPM disabling by kernel patching worked for me, at least for the main machine (my virtual machines inside this main machine still give the error after some time). I've been using the patch for almost a month without incidents. I had the problem inside a virtual machine after some days, but it didn't happen again yet (I'm using VMs but not for too much time like in the last time the problem happened).
I'm going to try to disable TRIM but it's going to take days for me to test if the VMs give any errors. Should sudo rm /etc/cron.weekly/fstrim be enough? Have you experienced problems installing ubuntu into your SSD? My ubuntu installation gives disk error in 8/10 tries. That is, I need to reinstall ubuntu 8 times in average for the installation to end without any problems. I didn't try to install ubuntu with the kernel patch because it's a lot of work to create a live CD instalation with a patched kernel, but maybe I'll do it some day. I also need to try virtualbox in place of virt-manager as kaihengfeng suggested. Problem is that I need to leave things open for days to notice these errors, so it's going to take time. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1746340 Title: Samsung SSD corruption (fsck needed) Status in linux package in Ubuntu: Confirmed Bug description: 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 Jan 29 01:07:39 lz kernel: [62984.375393] EXT4-fs error (device nvme0n1p2): ext4_find_entry:1442: inode #26607929: comm updatedb.mlocat: checksumming directory block 0 lz@lz:/var/log$ dmesg [62984.375393] EXT4-fs error (device nvme0n1p2): ext4_find_entry:1442: inode #26607929: comm updatedb.mlocat: checksumming directory block 0 [62984.377374] Aborting journal on device nvme0n1p2-8.

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.
