Re: `system clock stops operating' problem from 4-months old system.

:I have three machines which have been running DragonFly-Stable
:(i.e. pre-RELEASE systems) for about 124 days or so until it stopped
:updating the system clock.  Kernels are built from sources as of
:15th of February this year.  Unfortunately, I had to reboot them and
:update to the latest RELEASE as they are used as production servers,
:so I can't give much data for investigating possibly remaining bugs.
:When I logged into these machines, date(1) shows the same time for a long
:time(or probably not updating at all), and the number from
:  vmstat -i |grep ^clk
:didn't change.  I believe that the commit at 2005/03/27 11:25:10 PST
:should have fixed the bug(which means RELEASE have that fix too), right?

    It should have.  What we need, next time it happens, is a kernel
    core dump.  To do it get on the system console, kill 1 to drop into
    single-user mode, sync a couple of times, and then ctl-alt-esc into
    DDB and panic the box.

    The release occured after that fix so this sounds like a new issue
    that needs to be found and addressed.

    Did all the machine's system clocks stop after the same amount of
    uptime ?
