That can cause all sorts of problems, including RCU CPU stall warnings.
So I see the following in dmesg.1, courtesy of:
sed -e 's/].*$//' < /tmp/dmesg.1 | awk '{ if (oldtime != "" && oldtime > $2) print; oldtime = $2 }'
1.128644 -> 1.128642: Only two microseconds backwards, so not enough
to cause a stall warning (need about 21 seconds for that).
1.143582 -> 1.143575: Seven microseconds backwards.
316.386056 -> 421.191446: 104.8 seconds backwards, plenty to cause
all sorts of problems, including stall warnings.
311.122004 -> 316.338053: 5.2 seconds backwards, can cause all sorts
of problems, but not likely stall warnings.

Looks like a malformed list, which does look quite ugly. No idea
whether or not this could be related to backwards-going time, but
fixing the backwards-going time is a good first step.

One of your backwards-time incidents could cause both the RCU CPU stall
warnings and also the soft lockup I see there.
If this is an older system, it might have an unreliable TSC. If the
kernel is nevertheless using TSC, this sort of thing could happen.
The usual advice is to boot using HPET, but perhaps others on the
list have more specific advice.
