Hallo everyone,
as promised I bisected the issue and bisecting just finished.
See below for details.
As the candidate found by git-bisect sounds like an hit, I'm cc'ing
and Jan and Len, as there names are in the commit :)
Jan, Len: The Debian bug is here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776697
Please let me know if I can provide additional information; note that
I'm an noob in terms of kernel debugging :)
Next thing I try to compile the latest kernel in the Debian archives
with that commit reverted to see if I can boot a more recent kernel.

commit acead1b0fac5b10d0ae3f1cc5f7820b9f9f924f5

intel_idle: Add CPU model 54 (Atom N2000 series)
Add CPU ID for Atom N2600/N2800 processors. Datasheets
indicate support for this, detailed information about potential
quirks or limitations are missing, though. So we just reuse the
definition for the previous ATOM series. Tests on N2800 systems
showed that this addition is fine an can reduce power consumption
by about 0.25 W (personally confirmed on Intel DN2800MT).
