            Bug ID: 39141
           Summary: Freezing completely when adjusting date/time
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: aapmak at gmail.com
      Distribution: ---

I had a script running an ntpdate hourly and meanwhile, I intermittently had
this machine completely seizing up. To the point where only a tap on the reboot
button and/or powering off would work (which is rare in a Linux configuration).

The one element I could point out regarding this seizing up phenomenon was that
it would only occur when running Wine (typically, a game of some sort but not
limited to one individual title; it has happened with Banished, Heroes of the
Storm, Diablo III).

Last night it occured to me to simply remove that ntpdate script to see if that
would aleviate the problem; at first I suspected it was linked to the recent
shift from ASM to C in the Linux kernel but multiple kernel versions have
exhibited this phenomenon so that is unlikely. Again, the only constant seems
to be Wine.

Since removing the ntpdate script, the problem has not shown itself again. I
suspect there may be some issue with changing system date/time while Wine is
running. In particular, I suspect that any minor time adjustment to the past
might cause irregularities that end up causing very tight infinite loops or
something to that effect; since not even the keyboard responded when the
seizing up phenomenon occured.

This happened with multiple versions of time, all of which in the 1.7.4x
series.
