Unfortunately it shows the same behavior [0]. (To speed things up, I 
used a stripped down kernel config [1], while the first two posted boot 
charts used Ubuntu's stock kernels.)

I was surprised that the kernel directly built from the wq branch and 
the last "good" kernel from Linus' tree with the 33 patches applied 
don't show the increased boot time - shouldn't they all be the same?

About the system: Lenovo ThinkPad T510 with an Core i5-560m, 6 GB RAM, a 
SSD, and hybrid graphics (can boot from either the Intel HD or the 
Nvidia NVS 3100M - regression shows up with both).

The system is running an up-to-date Ubuntu dev release (Natty) with Xorg 
7.6(~3ubuntu7), Xserver 1.9.99.901+git20110131.be3be758(-0ubuntu6), and 
Plymouth 0.8.2(-2ubuntu17) FWIW.

Thanks,

Hernando Torque
