if I remove the isight_firmware module from the kernel
suspend wakes up the first cycle as it should.(I don't have
isight-firmware-tools installed, leading me to believe this might
be the issue with isight-firmware.ko.)

Now looking at dmesg I see:

[ 413.551845] uhci_hcd 0000:00:1d.0: PCI INT A -> GSI 23 (level, low)
-> IRQ 23
[ 413.551855] uhci_hcd 0000:00:1d.0: setting latency timer to 64
[ 413.551887] usb usb2: root hub lost power or was reset

Is that unexpected? It seems reasonable to me..


honestly I can't remember seeing this or not.
if this is normal then I'll leave it as is.

s2ram is working.. at first thought this was the cause,
but ended up not having anything todo with the real cause
of s2ram pausing.
