Interesting, I've been seeing this problem too on my Debian/testing
installation... And I know it USED to work at some point. :-)
adjtimex -p reported a tick value of 10006, but I found that
reducing tick temporarily to 10000 or even 9999 did not help
with this issue:

# adjtimex -t 9999
# vax -f /dev/null
