I noticed this recently, but don't remember it happening "a while
ago" (So it may be hardware going bad, or a break in -current, or
SMP borking ntpd...)  Anyone else seeing this?  My LX running 1.6
is fine, but this SS20 doesn't seem to like to keep time well.

(Could it be because I have an SM81 for cpu0 and an SM71 for cpu1?)

PS  pk, that spl patch for lock debug works great.  Haven't seen
a single "xcall... can't ping cpuX" since.
