Public bug reported:
Ubuntu 24.04 boots slowly when TPM is enabled on VMware Workstation.
## Environment
I saw this problem with the following VMware Workstation version.
- Pro 17.5.2
- Pro 17.6.4
Other versions are not tested.
I encountered this issue with the following distribution.
- Ubuntu 24.04
- Ubuntu 22.04
Not only the installed image, but also the ISO image causes this
problem.
## Details
Without TPM, Ubuntu boots smoothly on the VMware Workstation ( The firmware is
EFI ). There is no problem.
When the TPM is enabled, the Linux kernel adds several tens of seconds
to boot. This additional duration is before the syslog message. That
means I can not see any delay from the dmesg, while it is delayed.
By a quick investigation, I found that this delay happens during the EFI
stub. I could see the following messages while waiting for the kernel to
start.
```
EFl stub: WARNING: Failed to measure data for event 1: 0x800000000000000b
EFI stub: Loaded initrd from Linux_EFI_INITRD_MEDIA_GUID device path
```
I have a Fujitsu Laptop PC which runs Kubuntu. While it has EFI/TPM, I
don't have such a problem.
## Expected behavior
Linux kernel runs smoothly while TPM is available on the VMware Workstation Pro
17.x.
## Workaround
By turning TPM off, this problem disappears. Unfortunately, this is not helpful
because I am testing the Dual boot of Ubuntu and Windows 11 on VMware.
