Hello,
I am running four LBM benchmarks simultaneously on M5 (revision 7500) in
full system detailed mode, with M5 configured as 4 cores, private L1 and L2,
shared L3 cache. After m5term prints out LBM benchmark info and running for
a while, m5term prints the following message:
------------[ cut here ]------------

Is this a warning I can ignore? How should I fix this? Thank you very much.
