I have a Dell Precision 5510 with a NVME PCIe SSD with Ubuntu 16.04 and sometimes, I don't know when exactly, the file system falls or something similar and everything I can get from the laptop are messages on the screen(after pressing ALT + CTRL + F1) like:

[4433.524427] EXT4-fs error (device nvme0n1p3): __ext4_get_inode_loc:4043: inode #1319902: block 5243485: comm NetworkManager: unable to read itable block

[4433.526047] EXT4-fs error (device nvme0n1p3): __ext4_get_inode_loc:4043: inode #1319902: block 5243485: comm polkitd: unable to read itable block

And more like shown above. I have had this "crash" or "fall" more than 5 times. I have tried reinstalling Ubuntu, but this still happens. I have also installed Windows 10 in the laptop, and I haven't had any kind of crash related to the file system or the SSD. Does anyone know what is happening here? Is it a problem of my SSD or is it a problem of Ubuntu's drivers for NVME PCIe SSDs?

Thank you so much

Below there's more information of the system:

  • Do you know how to boot into recovery mode and run fsck? – heynnema Nov 21 '16 at 21:29
  • Yes, I have already run fsck on the device and it reports "clean". I don't think it's a corrupted file system, because I have installed ubuntu twice and I get the same problem. I think it's another cause, like problems with the driver's NVME SSD or a SSD's problem. Thank you for your answer – LuisG Nov 22 '16 at 9:29
  • Edit your question to include the output, in terminal, of sudo blkid and cat /etc/fstab. Do you have Intel processors? Also give me the output of dpkg -l *microcode*. – heynnema Nov 22 '16 at 9:42
  • Thanks for the info! Everything looks normal. Do you use Windows? Do you have any software installed there that allows you to read Ubuntu EXT4 partitions (which Windows can't do on its own). – heynnema Nov 22 '16 at 15:43
  • I have also installed Windows 10 on another partition and no, I don't have any kind of software to read EXT4 partitions. What do you think it is happening here? Do you know about any kind of incompatibility between M.2 SSD's and Ubuntu? Thank you for the answers – LuisG Nov 22 '16 at 17:12
