Mark Petersen, thank you for taking the time to report this bug and
helping to make Ubuntu better. However, I am closing it because the
requested patch is in Raring+ as per

raring.git;a=commit;h=1d17d17484d40f2d5b35c79518597a2b25296996 . It
would be best to utilize the supported Raring enablement stack to
utilize this patch in Precise following

time: Fix adjustment cleanup bug in timekeeping_adjust()
Tetsuo Handa reported that sporadically the system clock starts
counting up too quickly which is enough to confuse the hangcheck
timer to print a bogus stall warning.
Commit 2a8c0883 "time: Move xtime_nsec adjustment underflow handling
timekeeping_adjust" overlooked this exit path:
} else
return;
which should really be a proper exit sequence, fixing the bug as a
side effect.
Also make the flow more readable by properly balancing curly
braces.
