Hi, since updating to the latest snapshot my laptop (dmesg below) hang at the console after waking up from suspend to ram. The ttyC0 was displayed on both monitors, but neither typing at the console login prompt, nor switching to X worked. I was able to enter ddb with ctrl-alt-del and get a trace, which can be found at ftp://gmerlin.de/pub/ddb_screenshot.jpeg
