 should be sent to the mailing list available through the suspend2
 website, and not to the Linux Kernel Mailing List. We are working
 toward merging suspend2 into the mainline kernel.

-Q: Kernel thread must voluntarily freeze itself (call 'refrigerator'). But
-I found some kernel threads don't do it, and they don't freeze, and
-so the system can't sleep. Is this a known behavior?
-
-A: All such kernel threads need to be fixed, one by one. Select place
-where it is safe to be frozen (no kernel semaphores should be held at
-that point and it must be safe to sleep there), and add:
-
-            if (current->flags & PF_FREEZE)
-                    refrigerator(PF_FREEZE);

-Q: What is the difference between between "platform", "shutdown" and
-"firmware" in /sys/power/disk?
-
-A:
-
-shutdown: save state in linux, then tell bios to powerdown
-
-platform: save state in linux, then tell bios to powerdown and blink
-          "suspended led"
-
-firmware: tell bios to save state itself [needs BIOS-specific suspend
-         partition, and has very little to do with swsusp]
-
-"platform" is actually right thing to do, but "shutdown" is most
-reliable.
