I have a Thinkpad X200 with the latest build of libreboot installed on it. Maybe once every two months the system will crash and then fail to boot, and drop me to a root shell with instructions to run fsck manually, which I do.
Yesterday I updated my arch installation with pacman -Syu, and then cleaned up my disk with paccache -rk 2 and pacman -Scc. Upon rebooting (no crash involved) encountered that root shell with fsck message again. fsck found many more errors than usual, but appeared to handle all of them. Rebooting the second time left the system in its current state with this grub output:
error: unknown filesystem.
error: you need to load the kernel first.
error: you need to load the kernel first.I immediately pulled the SSD hard drive and made a backup image, fearing that it was failing. Then I wrote the arch live image to a flash drive and booted from that with the SSD back in the laptop. I started both a short and long SMART test on the disk, and both passed. Then I manually mounted the dm-crypt container that is my root filesystem and fsck'ed the underlying ext4 partition again, which returned no errors.
At this point I'm not sure where to go with troubleshooting, and could use an extra set of eyes going over this.

If I go back into the live-arch environment, decrypt and mount the SSD's root filesystem, arch-chroot into it, and then try to reinstall grub with grub-install /dev/sdb1 --recheck, it returns a similar error message:
grub-install: error: unknown filesystem****
In another chroot I just ran 'pacman -Qnq | pacman -S -' to reinstall all packages. Booting still hangs at the same place.
Let me know if I can provide any additional information. And I'll post back here if I happen to find a solution on my own.

I wiped the disk, recreated the partition table, and copied over the backed up system onto the fresh layout. Several system files were corrupted, and I replaced them with equivalents from my desktop's arch install.
I still don't know what caused the corruption or how I could have corrected for it or avoided it. I'm making replacing this SSD a priority as soon as financially possible. I'm also replacing my X200 with a different daily-use laptop, as I can't be confident in the X200's reliability past this point.
This issue is resolved but not solved.
