We have several IBM boxes (NetVista mostly) @work that would exhibit
similar behavior - run normally at first, then after a few hours the
system clock practically stops; I measured 2 minutes of wall-clock
time for a "sleep 1" to return, and up to 20 seconds for "usleep 1"...
Tried updating BIOS, kernel (4.3, 4.4, updates), some combinations of
boot time parameters (as in: clock={pit|pmtmr|..}, noapic, acpi=off
and the like), without improvement. We just gave up on those due to
the lack of time.

Solution from comment 18 may help (that comment was submitted after
we've given up, not sure if it was tried).

Cheers,
Zoran
