Hi Ikram,
It seems like your program is using a system call (#398) which has not been
tested or implemented in gem5. This can be because of a newer version of
the c library or compiler. One option is to ignore this system call and see
if your program still works. As a reference you can look at how the other
system call in your program is ignored (set_robust_list) in the gem5 source
code here: "src/arch/arm/linux/se_workload.cc".
