Then I tried to download ubuntu-18.04.2 LTS Desktop image, and did a fresh installation. Over there I couldn't find the lvmetad problem during startup.
Then I checked the kernel it installed with HWE - 4.18.0.15 and initramfs-tools - 0.130ubuntu3.6 version.
Then tried to download 4.15.0.46 generic kernel and removed the HWE kernel and then rebooted and see the issue persists.
Then tried to install initramfs-tools - 0.130ubuntu3.7 version with 4.15.0.46 generic kernel then the issue resolved.
But in my #92 , i tried with ubuntu-18.04.1 LTS desktop image and installed only initramfs-tools - 0.130ubuntu3.7 over there the delay issue still persist.
So my question, even in my case fresh installation of 18.04.2 works fine even after installed initramfs-tools 3.7 vers. But in fresh installation of 18.04.1 failed after installed initramfs-tools 3.7 vers.
