/dev/nvme0n1 Sabrent Rocket 4.0 1TB firmware RKT401.1

on Ubuntu 19.10 with an ASRock 300 Deskmini motherboard and a Ryzen 3400G CPU. The filesystem is ext4:

Linux elemental 5.3.0-24-generic #26-Ubuntu SMP Thu Nov 14 01:33:18 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

UUID=c1812230-91be-4a18-8055-c3b7c82fbbd8 / ext4 defaults 0 0
/dev/nvme0n1p2 on / type ext4 (rw,relatime)

When I run fstrim -v / as root, I get the following error message at the command line:

seth@elemental:~$ sudo fstrim -v /
fstrim: /: FITRIM ioctl failed: Input/output error

and the following kernel messages are logged:

I have tried setting iommu passthrough on boot but this doesn’t seem to help:

GRUB_CMDLINE_LINUX_DEFAULT="amd_iommu=pt avic=1”
