I've found that pciehp is taking a lot of time. It is better removing it before the suspend, and loading it afterwards. It goes from 14.5 sec to 8.5. I have this in /etc/pm/config.d/local: SUSPEND_MODULES="ath-pci pciehp" (the ath-pci because if not the wireless does not connect afterwards). Attached you have the kernel messages for a whole suspend/resume cycle, with and without removing pciehp. With the time recomputed with respect the "Back to C". HTH, Santi
