Comment (by alexander at linuxfromscratch.org):

 Many thanks for the screenshots, almost all of them are relevant. In fact,
 there are too many suspicious things so that there are now too many ways
 to dig.

  * on screen01.jpg, you caught __call_usermodehelper (i.e., trying to call
  * on screen02.jpg, you caught blk_unplug_work (some block device
 disappeared, huh?)
  * on screen05.jpg, there is ret_from_fork (presumably, /sbin/hotplug
  * on screen0{6,7}.jpg, there are three SCSI error handlers. They do match
 what I have on my linux-2.6.16-ide1 system, so if there is indeed
 something SCSI-related in the laptop, they are normal. But is SCSI (or USB
 storage) really there? And why three devices?

 So please debug further in the following order:

  * Boot with the "usb-handoff" parameter
  * If that doesn't help, try removing SCSI drivers and USB host
 controllers from the kernel config one-by-one, rebuilding the kernel and
 rebooting. The end result should be one of the following:
    * SCSI is red herring here, removing all of SCSI and USB didn't help
    * Driver FOO kills the boot process, let's remove it.
