But to let you know that you are not the only person, I witnessed pretty much the same thing. It happens *very* rarely but it does happen from time to time. I'm running 7.0-PRERELEASE with SCHED_ULE on i386 with 1GB RAM and ZFS on a GELI provider. The system is running Xorg7.3 with the radeon driver (I've come to blame Xorg 7.3 for all my recent problems ...) Anyway, it did *never* happen when I'm playing MP3s, but leaving mplayer paused for a couple of minutes I would return and the system was basically frozen. Sometimes after a couple of minutes it would unfreeze and replay all keystrokes and mouse movements but most of the time I'm too impatient to wait. I press the power button and nothing happens. A few minutes later it would do a regular shutdown. Strange things, indeed. The only way, I think I could track this down would be to hook up remote debugging via firewire and break to ddb, but I lack a second firewire laptop :( Cheers, Ulrich Spoerlein -- It is better to remain silent and be thought a fool, than to speak, and remove all doubt.
