I don't see anything too abnormal, except this:

ACPI: NR_CPUS/possible_cpus limit of 1 reached.  Processor 1/0x1 ignored.

I assume your kernel is compiled without SMP support, but you have an 
Atom CPU that supports hyperthreading. I don't know if it's related but 
you could try fixing that and see if it changes anything.
