ULE scheduler freezes kernel

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.
