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
