Your latest dmesg messages look interesting.
I've seen similar press space type problems during booting on one laptop I owned.
The solution I found was to add to grub the noapic or the nolapic grub boot parameter.
There are a number of grub boot options you can try as per the community wiki:
https://help.ubuntu.com/community/BootOptions
Thus if standard workaround grub boot options such as noapic or acpi=off dont work for you, some of the other common options could work for you.
When testing grub boot option you could use my answer here to temporarily add the kernel options at boot time.
How do I set 'nomodeset' after I've already installed Ubuntu?
irqpoll:
from the wiki: Changes the way the kernel handles interrupt calls (set it to
polling). Can be useful in case of hardware interrupt issues.
irqpoll [HW]
When an interrupt is not handled search all handlers
for it. Also check all handlers each timer
interrupt. Intended to get systems with badly broken
firmware running

Thus - and since you have a custom built computer - it is very likely to be one or more components that make up your computer. To discover which one will require a bit of detective work.
The easiest way would be just to simplify you computer to the basics - use a fixed keyboard, simple mouse, onboard graphics, onboard ethernet and nothing else. i.e. pull out all the PCI cards/USB components you are using. Then add each one back in one at a time.
If you find that you still need irqpoll on a simplified build - then you'll need to take a closer look at your motherboard. Look at the manufacturer site and see if there are any firmware updates - most probably you'll need to dos-boot to flash these.
Check file owner and permissions of the init script on the root filesystem:
# ls -l /sbin/init
-rwxr-xr-x 1 root root 167192 Jan 18 2013 /sbin/init

Try the following:
/etc/initramfs-tools/conf.d/resumeRESUME=UUID=xxxwithRESUME=nonesudo update-initramfs -u(create the file if it does not exist and just add
RESUME=nonein it)The file should contain the UUID of your swap partition, you can check this with
sudo blkid | grep swap.I found the following bug on launchpad which is supposed to be Lubuntu specific but the commands above also resolved the same issue on my Xubuntu installation.
See comments #27 and #28.
This file seems to be related to hibernate/suspend, I can confirm
suspendstill works on my system after the changes.
