>Description:
Spontaneous reboot with no other indication in logs except for message
on reboot.  Please let me know if you want the savecore.  I did check to
see if there was a report already on this, forgive me if I miss it.  If
this is solved in a more current version, please let me know.  We already
plan to install 7.0-RELEASE when it is available.

Thanks!

 This happened to me as well today,
 running FreeBSD 7.2 Release on AMD64.
 
 I was doing I/O and I have a large file located on the
 raidz1 pool however it is not really reproduciable as the system
 ran fine for some days before.
 
 Regards
 
 Carsten
