I'm trying to compile the XEN options on a host server on 9.2-R and get the
following failure during make:

*** [evtchn_dev.o] Error code 1

Stop in /usr/src/sys/amd64/compile/HOST0.
root_at_host0:/sys/amd64/compile/HOST0 #

It compiles fine without these options:

options         NO_ADAPTIVE_MUTEXES
options         NO_ADAPTIVE_RWLOCKS
options         NO_ADAPTIVE_SX

# Xen HVM support
options         XENHVM
device          xenpci
 
Are these options depricated now?

thanks,
