It appears your system hit a large number of ACPI errors when you went to suspend.  When you resumed, it hit this warning:

void ktime_get_ts(struct timespec *ts)
{
        struct timekeeper *tk = &timekeeper;
        struct timespec tomono;
        s64 nsec;
        unsigned int seq;

        WARN_ON(timekeeping_suspended);


when it was in the middle of a fork call.

I'm guessing this only happens during suspend/resume?
