One thing I noted in your first message, Chris, was that it usually happens when a cron job is running. I immediately thought of two possibilities: 1. One or more of the cron jobs are running a process that is "tickling" a driver that doesn't work as well with the newer kernel as it did with the previous one. 2. A scheduled job is doing something CPU-intensive that could be making the system overheat. (I suppose load caused by a given job might be worse under wheezy than it was under squeeze.) Unfortunately, I didn't keep the earlier messages and can't refer back to them to be certain whether or not my addled brain is remembering the details properly. I hope you find the gremlin and oust him! Regards, J. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
