Hi Tom,

Recent changes to the email setup for the mailing lists (actually all of
freebsd.org) has hosed me.  I am unable to post this report as my email
is rejected saying that it cannot find my hostname.  I would appreciate
it if you could forward this to the list.

Thanks,
Sean

amd64 -CURRENT system has crashed now several times in the last 2 days. 
Ever since the change to SCHED_4BSD and PREEMPTION.  I certainly hope
this is fixed before 5.3-RELEASE.
