** Description changed: 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 the VMware Workstation ( The firmware is EFI ). There is no problem. + 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.
