I have a very big issue with Ubuntu. I have 20.04 installed on an M2 NVME Kingston SA2000 with ASRock b550 Steel Series. Sometimes it happens that Ubuntu crashes. I can open terminal and type a command, but any instruction does not finish.

Chrome is not responding. Ctrl+Alt+F1 does not solve it. Alt+PrtSc+ R E I U S B does not reboot the system - I get messages about the NVME error (device not ready).

Only hard reset helps, but then the system does never get alive. After hard resetting and mounting in safe mode, I get to initramfs with the message that the root filesystem on nvme0n1o5 requires a manual check.

I have completely cleaned the NVME and installed Ubuntu again, losing all progress. But I keep getting errors again and again (once a week).

What may I try so I don't have to reinstall the whole system every week?

    I'm not sure if it's a typo or if you actually have you used it this way, but it's Alt+PrtSc+R E I S U B instead of Alt+PrtSc+R E I U S B. – BeastOfCaerbannog Mar 15 '21 at 12:09
  • You were supposed to run the fsck disk utility (while booted from a live USB device in "Try Ubuntu" mode) to find and fix errors on the disk. Have you? – Levente Mar 15 '21 at 12:53

This sounds like a hardware defect, most likely either your RAM or your SSD.

First check your RAM with memtest86: How do I run memtest86+?

Then use the Smartmontools to check your disk(s) / SSD: https://help.ubuntu.com/community/Smartmontools
