Is this bug a regression? Did this issue start happening after a
specific update/upgrade? Was there a prior kernel version where you were
not having this particular problem?

Title:
Booting is slower when TPM is enabled on VMware Workstation.
Status in linux package in Ubuntu:

Bug description:
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 Ubuntu, but also the installer ISO images cause this
problem.
My installed Ubuntu is booted from GRUB.
## Details
Without TPM, Ubuntu boots smoothly on 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.
## How to reproduce
1. Set up a VM with TPM on the VMware Workstation 17.6.4 (I am using it on
Windows 11).
2. Bring either ubuntu-24.04-live-server-amd64.iso or
ubuntu-24.04.2-desktop-amd64.iso as boot disc.
3. Boot from ISO.
The time difference between booting with/without TPM is about 1
minute.
## 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.
