I just completed my first LVM on LUKS Arch installation and it's working fine but,I have one question. When it boots, I can see the kernel loading then it prompts for the encryption password. That's expected. However before you can enter the password, the screen goes dark for 10 seconds and the prompt comes back. After you enter the password, it says it's pausing for 10 seconds while waiting on the disk but, it doesn't pause. It boots normally. Is this normal?
Within the LUKS container, I'm using 3 LVM volumes for root, home, and swap. I'm using a GPT partition table with a legacy BIOS (no UEFI) and syslinux as the boot loader. The kernel options in syslinux.cfg are:
cryptdevice=/dev/sda3:mydisk root=/dev/mapper/mydisk-rootvol rw
As I said, except for this quirk, the system boots normally.

There is no delay when I'm booting my LUKS partitions however I'm not using LVM.

Sure, it's waiting up to 10 seconds for the device to appear. Working as intended.

I see a similar thing, but instead of the screen going black it continues to print a few lines of kernel modules loding after it prompted me for password, then I have to type the password in while it's counting up seconds, so each "**" I type is removed by the seconds counter.
It works, just looks a bit "messy".
I have "just" LUKS on /home, no LVM.

@MickeyRat: The 10 second black screen sounds like some kind of graphics initialization. Can you post the output of lsmod, dmesg and lsinitcpio -a /boot/initramfs-linux.img?
@brain0 thanks. Spot in.
