Hi Tom, My guess is that you're using a newer version of GLIBC which calles different syscalls than the versions of GLIBC that have been tested with gem5. I believe 278 is mq_notify. You can try to update the syscall implementation to ignore the syscall and see if the application still works. See https://gem5.googlesource.com/public/gem5/+/refs/heads/develop/src/arch/arm/linux/se_workload.cc#404
Another possibility is that you're using a 32-bit emulated process with a 64-bit binary, or something has gone wrong with whether it's detected as Arm32 or Arm64. In the 64-bit version, 278 is getRandom, which is implemented. See https://gem5.googlesource.com/public/gem5/+/refs/heads/develop/src/arch/arm/linux/se_workload.cc#762 Hope this helps!
