Subject2.6.35-rc6: S2R hangs + WARNING: at net/mac80211/scan.c
Date
config can be found here: 
https://bugzilla.kernel.org/show_bug.cgi?id=15673

1.) suspend to ram very often does not work in 2.6.35-rc6 (but sometimes it does work!).
S2R very often results in a black screen with backlight on.
a dmesg of a successful S2R cycle can be found in above bug report.

this is a regression against 2.6.34.x that did survive tens of S2R cycles.

2.) Also I found this in dmesg:
