Alright, I have managed to trace this.
http://johannes.sipsolutions.net/files/hibernate-delay-dmesg.txt
has the dmesg, you can clearly see the delay: [50265.143330] ACPI: Waking up from system sleep state S4 [50265.679141] HDA Intel 0000:00:08.0: restoring config space at offset 0x1 (was 0xb00006, writing 0xb00002) [50265.689525] forcedeth 0000:00:0a.0: restoring config space at offset 0x1 (was 0xb00003, writing 0xb00007) [50265.699775] ahci 0000:00:0b.0: restoring config space at offset 0x1 (was 0xb00403, writing 0xb00407) [50286.294910] pci 0000:00:03.2: PME# disabled
I managed to get an entire function trace between
[50265.143330] ACPI: Waking up from system sleep state S4
and
[50290.439040] Restarting tasks ... done.
which I've uploaded to
http://johannes.sipsolutions.net/files/hibernate-delay-trace.bz2
(WARNING: uncompresses to 574MiB!)
I'm not sure why the timing in there doesn't show the delay, Steven was taking a look at that.
