Comment(by Quozl):

 Replying to [comment:6 pgf]:
 > the moral?  don't stress the freeze/unfreeze mechanism so hard.

 Why are DCON interrupts missed during the freeze?  How will we prevent
 unfreeze from potentially being requested within this critical time?
 Should the kernel implement a delay to prevent a race?

 (If there was only one process manipulating
 /sys/devices/platform/dcon/freeze it would be alright, but there are
 several; powerd and diskspacecheck at least.)
