Sorry for the late reply, I'm behind with reading mails. 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,

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 :(

It is better to remain silent and be thought a fool,
than to speak, and remove all doubt.
