jimmy: you might have a different problem because the delay that my
original bug report is describing happens after grub, not before it.

Title:
Adam, you're right in your original post that initrd is the cause of the delay.
Other non-Ubuntu based distros do not have the long 50 secs wait to boot OS at
usb. (same kernel)
It's just 13 secs vs 50secs. (haven't tried Debian distros).
One would think after 5 years, something ought to be
Someone who can still reproduce this issue should open a report
upstream. The kernel devs will never take a look at this otherwise.

Title:
Grub
I can report that this bug is still present in 14.04 Server Edition.
I am running an HP Proliant MicroServer G1610. The OS boots from a
Sandisk Cruzer. It is a full installation, not a LiveUSB.
The delay between POST and GRUB is over 5 minutes. Reinstalling Grub
does not resolve the issue.

Same here with ubuntu 13.04 installed in a USB stick
It is a fast stick. Boots in some computers in a few seconds, but in others it
takes 6-7 minutes to boot.
The main delay is when loading initramfs, it takes 5+ minutes.
After that, boot sequence is normal.

Is this an error similar to the one in the link?

I also noticed the slow reads when trying to create a multi-boot USB stick.
For a 38MB initrd it takes over 1 minute to load on all pcs tested. Using
syslinux, the same initrd (from the same stick) is loaded in less then about
5seconds.
So this is definitely not a Bios issue.

I do not think that the issue is related generally to bad bioses not
supporting USB2.0. Especially in my case I have an option in Bios to
either set USB ports to 2.0 or 1.1 at boot. I can also clearly see that
it becomes faster when select 2.0 but its still horrible slow to load
the kernel+initrd
