The common thing I noticed with both logs is that there was an acpid message regarding a USB device being disconnected shortly before the lockup, when there was nothing unplugged at that time. I use a streamzap USB IR receiver which appears to then reconnect afterward. Does anybody have a suggestion on where to start troubleshooting this? When I have had lockups like this in the past I have never really had any useful logs, so this is a first for me.
