+qemu-system-riscv32 cpu_transaction_failed cause Infinite loop when write mstatus ~"target: riscv"
+Description of problem:
+I wanna run FreeRTOS riscv, and use the FreeRTOS/Demo/RISC-V-Qemu-virt_GCC/Makefile to build elf.\
+When qemu execute to write mstatus as 0x1888(enable Interrupt, MIE:1, MIP:1, MPP:3), there is no response.\
+https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/main/portable/GCC/RISC-V/portASM.S\
+line 274: csrrw   x0, mstatus, x5                 /* Interrupts enabled from here! */\
+opcode is hex 30029073\n
+I use pstack to trace qemu thread, there is only one thread is active, and cpu loading is 100%.\
+then I use gdb attatch <pid> to trace the active thread, and it has a loop\
+cpu_loop_exit call siglongjmp and back to sigsetjmp in cpu_exec (cpu=cpu@entry=0x55e2294e4070) at ../accel/tcg/cpu-exec.c:936
+Steps to reproduce:
+1.download FreeRTOS and build FreeRTOS/Demo/RISC-V-Qemu-virt_GCC\
+2.run qemu with gdb\
+3.hang when writing mstatus
+Additional information:
+I find that my issue occur when mtvec is zero and timer interrupt occur when writing mstatus(riscv_cpu_do_interrupt)\
+Although it should jump to 0x0 rather then hanging in while loop.\
+expected flow :cpu_handle_interrupt->check_for_breakpoints->break\
+actually flow: cpu_handle_interrupt->check_for_breakpoints->infinite loop\
+Qemu build command: 
+```
+./configure --target-list=riscv32-softmmu && make
+```
+
+pstack for qemu (only need to debug Thread 3)

+
+I also build a very simple elf for qemu-virt-platform, just contain boot-loader and write mstatus as 0x1888, it can't reproduce.\
+I also build different qemu version such v6.0.0, it still can reproduce.\
+I has modify the march to the most simple arch:rv32i, is still can reproduce.
