I'm on Ubuntu 20.04, and after updating to the HWE 5.8 kernel recently I have also been suffering my nvme drive becoming read only after a period of time. I have now switched back to the 5.4 kernel and not suffered the issue again.
I am on a single disk system so had to run dmesg --follow remotely on another machine to retrieve log information. Here is a pastebin of around the time my system locks up https://pastebin.ubuntu.com/p/FKsJV8VwRw/ (note it has similar errors, a timeout aborting, then a reset, then i have a call trace etc). Here is a pastebin of the smartctl output https://pastebin.ubuntu.com/p/W9w2nHYhd2/ the drive itself appears to be fine and not failing (it does seem to increment "Error Information Log Entries" when this lockup happens - but when viewing the error it is just full of 0xffff). System info when the lockup happened: Machine: Dell XPS 13 9360 Drive: THNSN5512GPUK NVMe TOSHIBA 512GB Kernel at the time: $ apt policy linux-image-generic-hwe-20.04 linux-image-generic-hwe-20.04: Installed: 5.8.0.36.40~20.04.21 Candidate: 5.8.0.36.40~20.04.21 Version table: *** 5.8.0.36.40~20.04.21 500 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages 100 /var/lib/dpkg/status 5.4.0.26.32 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages Let me know if I can provide any more info :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910866 Title: nvme drive fails after some time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1910866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
