Hi @anon62096739,

More information would be useful, see How to provide good information

However, according to this answer on Stack exchage:

There is a bug which matches everything you describe (including the separate comments when I wrote this answer). The bug was introduced in upstream kernel v4.14, which was fixed in v4.17 and v4.16.8.

kernel/git/stable/linux.git - Linux kernel stable tree

If you still do not have a new enough kernel, and you don’t want to install an older kernel (switch to the linux-lts package mentioned in the Arch thread below?), there is a workaround. You can add the option “scsi_mod.scan=sync” to the end of your kernel command line, e.g. in GRUB.

I have no idea if it’s the same bug or if it’s something else, though.
