99% of the time, this is a hardware fault.  You probably won't be happy
to hear that, but it is almost always the case.

Yikes, a kswapd panic is a critical error.  If I were you I'd be
rebooting systems immediately when that happens.  Please post such
errors here: when any kernel instability occurs, it is *always* the
first error which matters most (because subsequent errors are always
going to suffer from the suspicion that they are side-effects of that
first problem.)

memtest86 is a good first diagnostic in this sort of case.
