Hi Amir, The warning is coming from here: https://gem5.googlesource.com/public/gem5/+/master/src/arch/riscv/locked_mem.hh#118 (BTW, it's always helpful to grep for the warning or panic in the code to see what generates it.)
I think this is a bug in RISC-V SE mode, but I'm not sure exactly what the problem is. You're running multiple copies of the hello binary. I could be that they are all using the same physical address for some reason (though, this shouldn't be the case). I would try running with the Exec flag to see what instruction is causing this problem (and stop running after 186707000 ticks, too, so the log doesn't get too long). Let us know if you track down the issue.
