Unable to boot after power failure during package upgrade

I am having issues booting after power failure during

pacman -Syu

My initial thought was that the issue was caused by a Linux update that was interrupted, but booting into the Arch ISO, mounting the root partition, and lsing the moint point hangs with some I/O errors, so I couldn't get the point of rebuilding the image. Any ideas of how to diagnose this? Is this a dead SSD?

The error during normal boot is

ERROR: device '/dev/sda2' not found. Skipping fsck.

EDIT: I should add that the boot partition is on the same disk, and appears to be working fine.

Please post the output of dmesg containing the IO errors and the output of a S.M.A.R.T test if the device supports it.
If not just `smartctl -a /dev/$device` either in code blocks or to a pastebin.

The SMART self test seems to have passed: https://ptpb.pw/OUOj

I can't get input to work in the emergency shell (this has always been an issue), so can't get the dmesg from that, but from the Arch ISO:

$ fdisk -l

Output: https://ptpb.pw/Gc9O

$ mount /dev/sda2 /mnt
$ fdisk -l

The second fdisk call hangs. The output of dmesg a few minutes later: https://ptpb.pw/5PoI
