Huh?

Ed. Filesystem totally hosed.  >:(
Reinstalling, pretty keen to know what went so horribly wrong here…

Same exact issue here. What did you do with yours?

[Stepinsky]

Which bios version do you have? There are known problems with latest bios (4.6.x mainline branch) when accessing hard disks:

v4.6.x BIOSes need to have MSI disabled, due to signal races causing disk write commands timeouts.

Maybe your issue is related to this bug?
