I tested your patch with CONFIG_NO_HZ=y, but it still hangs while suspending to disk (before the percent saving). But one discovery. I get tired of all these hangs, so I decided to press some keys and the power button. Accidentally, the suspend proceeded and successfully suspended! I tried many more times, and discovered that to proceed with the suspend, hit any 4 keys slowly. (e.g. "F1 F2 F3 F4", or "1 2 3 4"). My .config has CONFIG_NO_HZ=y and CONFIG_HIGH_RES_TIMERS=y, but I suppose CONFIG_HIGH_RES_TIMERS=y gots nothing to do with the hang. I went back with my vanilla 2.6.21-rc5 with Maxim's patch, and with hitting the keys, I could suspend to disk with CONFIG_NO_HZ=y and CONFIG_HIGH_RES_TIMERS=y.
