OK, thanks.
I'm rather buried in timer patches at present. It would be best if you could test new work in the context of those patches.
They are at http://www.zip.com.au/~akpm/linux/patches/timers/
The applying order is
posix_timers-CLOCK_MONOTONIC-fix.patch jiffies_to_timespec-fix.patch do_timer_overflow-locking-fix.patch lost-tick-fix.patch
