CONFIG_PREEMPT is not set

Yep, looks good so far (at least in my virtualized test environment):
2.6.39-rc4 with your patch applied survived 100 suspend/resume cycles
w/o locking up.

Just out of curiosity: Was this a new issue in 2.6.39-rc4 ord could
this fix be backported to 2.6.38?

Thanks,
Thilo
