Personal experience.  When I burn a CD, my machine loses serial 
interrupts, and NTP claims to have lost sync.  When I complained about 
this on c.p.t.ntp, someone suggested looking at hdparm, and sure enough 
unmasking made the problem go away.  Now, the clock loss was not nearly 
as massive (say 5 minutes from burning 3-4 CD's), but I still think it's 
something the OP should pursue.
