[Bug 630432] [NEW] cpuidle in linux-image-2.6.35-19-generic crashes kernel on boot

[Martin Emrich]

Public bug reported:

linux-image-2.6.35-19-generic fails to boot on my Lenovo Ideapad S10-3
(Intel Atom N450). linux-image-2.6.35-17-generic boots fine.

While trying out 2.6.36-rc3 from kernel.org, I noticed the same problem.
After just disabling cpuidle support in this kernel, it boots up fine. I
noticed that the most obvious difference between -17 and -19 is the
cpuidle driver.

Maybe blacklisting the Atom N450 or the N10 chipset in the cpuidle driver might help for maverick.
