Historically, most suspend problems are driver
issues. If you have
some time, try unloading individual modules before attempting the
suspend. Once you're able to suspend reliably again, it should be
clear which module is at fault. I'd start with the usb audio driver.
Time I have... I have to do something, it is crashing randomly when I
hibernate. It is a nuisance, hibernation is an important part of my work
Then I would do "rmmod snd_usb ; rmmod snd_usb_audio", hibernate, and
on thawing I would have to modprobe them. Or perhaps "rcalsa stop"?
Or seeing the last message before the crash, should I try another driver
instead, perhaps the network?
Or, if you have suggestions about more printk messages to add somewhere,
say so :-)
I forgot that when it crashes, it would be at the point of the next
messages that did not print, not at the last message printed. Then the
important messages would be these, related to sound and usb - as you said:

devices complete after 2646.655 msecs
Thus my plan will be to wait for the next crash, take the photo, and then
add a script to stop sound and remove those modules, plus undo on restore.
