I have. There was a time when my freezes were only on resume from hibernate, and hibernate traces were the only way I could find to get a log of the hibernate process. What is odd, however, is that when I get a hang on resume from hibernate, reboot, continue using the same hibernate file and boot successfully, the trace file doesn't show the failed resume attempt. I would expect to see either a large chunk on the graph where the driver
hangs, or to see a point in the trace where the drivers
repeat themselves from restarting the resume from hibernate process. I see neither in the trace.
