Hello everyone,

since updating from 3.6.11 to the latest stable kernel 3.7.9 on my thinkpad t420 the boot sequence halts for ~7 seconds before resuming.


Here's an excerpt from my dmesg where you can see the issue: http://bpaste.net/show/79228/ .
And here's the .config for the 3.7.9 kernel: http://bpaste.net/show/79230/
And here's the .config for the 3.6.11 kernel: http://bpaste.net/show/79231/

Besides that everything seems to be working fine. :)

No one? :(
Anyway I tried with kernel 3.8.0 and it has the same exact issue.

Not really an idea, but it could be related to the mouse driver, because the delay happens directly before the mouse driver message.

You have several mouse drivers enabled:
CONFIG_MOUSE_PS2_ALPS=y
CONFIG_MOUSE_PS2_LOGIPS2PP=y
CONFIG_MOUSE_PS2_SYNAPTICS=y
CONFIG_MOUSE_PS2_LIFEBOOK=y
CONFIG_MOUSE_PS2_TRACKPOINT=y
CONFIG_MOUSE_PS2_ELANTECH=y
CONFIG_MOUSE_SYNAPTICS_I2C=y

What happens if you disable all the mouse drivers except the one you seem to really need (CONFIG_MOUSE_PS2_TRACKPOINT), of course including its dependencies?
You can also try to disable mouse support completely (just for a test - you will need to change to a console and configure for mouse support again afterwards).
