[Bug 670597] [NEW] Kernel hangs on boot for about 30 seconds before init

[Volker Maibaum]

Public bug reported:

After loading the kernel the system hangs for about 30-35 seconds. I suspect that it has something to do with the graphic card.
I think the problem didn't exist with the initial 10.04 version and definately not with 9.10. 
The problem already occured with a recent 10.04 version (but I had activated some beta repositories and I don't remember which kernel was installed)

Here is the output of dmesg that shows the delay:

I found a similar problem here (with a radeon driver):
http://bugs.freedesktop.org/show_bug.cgi?id=25506

I tried with kernel parameter: i915.modeset=0 and i915.modeset=1 but
this had no effect on the delay.

I will try the mainline kernel later to see if the problem exists there
too.
