cryptsetup hanging?

Anyone ever have cryptsetup just start hanging after entering password on boot? This seems like it's going to be a fun issue to try to resolve...

  • How long do you wait before you declare it hung?

    Sometimes decryption takes up to a minute depending on your system specs and optimizations.

    I suggest booting from a live disc and trying to unlock it from there.

    • 10m is when I throw my hands up. Normally it takes under 20s.

      • That's more than a reasonable period of time to wait.

        Can you run a SMART check on the drive from a liveCD? memtest86?

      • Paste the output of cryptsetup benchmark

          • how about systemd-analyze and cryptsetup luksDump <lukspart> | grep Slot

            • I'm not using systemd. Grepping on Slot doesn't return any results.
