    Ok, thanks for all the debugging info. There are two issues here:

1. Embedded controller read times out during boot.
As seen above, during the probe of your flash key, the EC hits higher and
higher delays until finally timing out.  The issue is that ACPI acquires
Giant and so does CAM (which is probing your flash drive).  Try booting
without your flash key inserted and see if the error goes away.  I am
working on a patch for ACPI to run Giant-free that should address this.
It's almost done.

2. Error messages for power switching consumer.
These are harmless but I'll remove them.  The power state routines try to
power down your USB7 and built-in modem since no driver attached them.
However, they don't offer power control via ACPI so the attempt returns a
harmless error message.  I'll add checks for this.
Thanks for the help,
Nate
