You have me at a disadvantage chazdg24. I did not mention a graphics card.
As stated at viewtopic.php?f=46&t=170974
the cause for the boot delay was a keyboard with an inbuilt usb sound card plus two usb slots. Dmesg shows a 49 second delay. As soon as another keyboard was used, the boot delay did not occur.
Naturally I would like to continue to use my favourite keyboard and I have been working at disabling these unwanted extra facilities. Udev rules, blacklists and so forth have so far had limited success.
