Out of curiosity - when you have experienced this bug, have you been running the Chromium browser (or Google Chrome) when you hibernated? I've been able to replicate, fairly repeatably, this same BUG, by attempting to hibernate with chromium running (I receive the exact same backtrace). Without chromium running, I do not experience this failure *at all*. Best, Victor -- Victor J. Orlikowski <> victor.j.orlikowski@alumni.duke.edu
