Ubuntu 24.04 freezes with "nvme nvme0: I/O" timeout error
https://askubuntu.com/questions/1557696/ubuntu-24-04-freezes-with-nvme-nvme0-i-o-timeout-error
I am running Ubuntu 24.04.3 LTS (codename "noble") in an ASUS Vivobook 15. My kernel version is 6.14.0-33-generic according to the output of uname -r.
Ever since I got this laptot, my Ubuntu system would sometimes "randomly" freeze. This would occur rarely enough that it didn't represent a problem. However, today I exeperienced an annoying sequence of repeated freezes which got me looking into the problem more closely.
I ran dmesg -w and waited for the computer to freeze. It eventually did, precisely after the following output:
nvme nvme0: I/O tag 4 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 7 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 9 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 4 timeout, aborting req (WRITE), QID 0, size 4096
nvme nvme0: I/O tag 10 timeout, aborting req (WRITE), QID 0, size 4096
So it seems the freezing was triggered by an error in a write operation of 4KB. I found two other people with this issue (1, 2), but their final solution was to change the SSD, which is not economically viable for me.
After a force shutdown (the only way to handle the freezing), I ran sudo dmesg -T | grep -i nvme -n -A5 -B5, since the issue was comming from nvme. The boot section of the output looked normal:
nvme nvme0: pci function 10000:e1:00.0
nvme nvme0: allocated 64 MiB host memory buffer (1 segment).
nvme nvme0: 8/0/0 default/read/poll queues
I tried changing the GRUB_CMDLINE_LINX_DEFAULT from
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"
to be frank simply because ChatGPT recommended it (I know this is embarassing). This only caused freezings to become worse, so I undid it.
Now I've changed GRUB_CMDLINE_LINUX_DEFAULT to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
because in one of the hyperlinks I gave above someone recommended it. I have not experienced any more freezes, but it's only been a couple of hours so the issue might continue.
In case it's useful, here's the output of sudo smartctl -a /dev/nvme0:

What's the root cause of my errors? Can I fix them in some way that does not involve buying a new SSD?
