 The PR is available at: http://www.freebsd.org/cgi/query-pr.cgi?pr=166071.
 
 Below is some more information about this particular bug. I thought this
 could be a kernel bug, but maybe it could be a bug in the program that the
 9.0-RELEASE kernel exposed.
 
 If the faxq and hfaxd processes are started (via their startup script) and
 then faxgetty is started all appears fine.
 
 However, while sending a fax the faxgetty process is again at 100%. The
 truss output for faxgetty is not included because it is the same as stated
 earlier. After the fax has completed, faxgetty remains at 100%.
 
 Should this still be considered a kernel bug or should I try contacting the
 HylaFAX maintainers?
 
 Note that the configuration is run in a jail with a USB (cuaU0, MultiTech
 MultiModem MT9234ZBA-USB-CDC) and serial modem (cuau0, MultiTech MultiModem
 MT9234ZBA-NAM). This configuration did work under 8.2-RELEASE-p6. Also,
 this message is shown during the initial setup probe: stty: stdout appears
 redirected, but stdin is the control descriptor.
 
 Thank you for your time.
 
 v/r,
 Ryan
