This seems to be solved with RELENG_6 :

root@:/usr/obj/usr/src/sys/RENE 

% sysctl kern.sched.name
kern.sched.name: ule

% uptime
 3:35pm  up 3 days,  1:17, 6 users, load averages: 1,00 1,02 1,00

And it even survived an OpenOffice portupgrade. :)

ULE scheduler freezes kernel

[Rene Ladan]

Hi,

I was trying the ULE scheduler again on my single i686 5.4PRE laptop,
but it causes the kernel to freeze after some time (=30 minutes): the
kernel does not even respond to opening/closing the lid when booting
verbose (normally it displays acpi_lid0: Lid {opened|closed}).
Having some disk activity (e.g. portupgrade) seems to catalyze this
behaviour.  Only a full power reset gets the laptop running again.  I do
not have this problem with the 4BSD scheduler.
