Ryzen PC Backup

I finally decided to perform a backup of my new Ryzen PC running Fedora 26. Normally I wouldn’t leave it too long between backups especially if I have made significant changes. My new PC presented me with a little bit of an issue, I couldn’t run my backup software.

I tend to use Clonezilla to take/restore system images. I’ve used it for years and it has been working well for me. That was until I tried to boot it on my Ryzen system. It was hanging with tpm_tis and tpm_crb errors.

The arch wiki states that “Support for TPM 2.0 is still incomplete (both on the kernel and in userspace), and no known work flow for TPM2 exists at the moment.”

It would appear that I had enabled the TPM option in the bios and I have TPM 2.0 hardware.

The Workaround
Clonezilla 2.5.2-20 (Debian – Kernel 4.11.11-1+b1)

  1. Disable TPM in the bios.
  2. Boot from a CD (non-uefi) and run Clonezilla in graphics safe mode.
  3. Having successfully booted Clonezilla, perform backup as normal.
  4. On completion of the backup re-enable the TPM hardware in the bios.
