   Sorry for lately reply
   I check this issue, for SMP, the CONFIG_ARCH_FPU shouldn't enabled, but with 
configure, I can see
   CONFIG_ARCH_FPU=y
   the FPU context switch for FPU is little sophisticated and need to be support
   for the present, you need to disable the option in 
boards/arm64/qemu/qemu-armv8a/configs/nsh_smp/defconfig
   CONFIG_ARCH_FPU=n 
   I check with myself qemu(6.2.0 and 7.2.2) and not reproduce the issue again.
   please check with your environment, if you confirm the issue is fix, I will 
push a PR to fix it
