Unfortunately this is reported to have broken hibernation on two machines: an EeePC 1002HA and an Ideapad S10-3.

Noticed on Debian squeeze (which is based on v2.6.32.y), confirmed with unpatched v2.6.32.45 and v2.6.33.18. Backing out the patch mentioned above avoids trouble. A newer kernel (based on v2.6.39.y) does _not_ exhibit the same problem, so it looks like the problem was introduced in backporting. http://bugs.debian.org/622259 has details. Ideas?
