What were you trying to do that didn't work?
Start Windows 11 with no TPM error
How reproducible:
Always with swtpm 0.8.0, never with swtpm 0.7.3
See below. Happens with RHEL9.5 (and centos 9 stream), not with RHEL 8.6
Steps to reproduce
- Create a Windows 11 VM with TPM (tpm-tis or tpm-crb, doesn't matter)
- Open `tpm.msc` or any TPM tool (like tpmtool), everything should look fine
- Open Event Viewer, go to Windows then System
Expected results
No errors
Actual results
TPM error 27: initialization failed, TPM might be in failure mode
