using command line:
cp -ruvax /some/path/* .
where /some/path/* is approx 1 Tbyte of large and small files,
cp crashes ( and so does rsync )
I do not think it is actually related to these commands ( kswapd also occurs in
source or initiator of the BUG entry )
hardware is x86-64, amd cpu. memory 12 GB ddr3
kernel:

this is dmesg output :
