Description of problem:
On win10-32 guest, hit BSOD when do system reboot during iozone test,
encountered by automation, and QE only hit once so far. and sorry no dump file was saved.
Stop code: CRITICAL PROCESS DIED

The automation job name:
block_during_io.iozone_stress.data_disks.send_shell.with_reboot.

Version-Release number of selected component (if applicable):
kernel-5.14.0-70.13.1.el9_0.x86_64
qemu-kvm-6.2.0-11.el9_0.2.x86_64
seabios-bin-1.15.0-1.el9.noarch
virtio-win-prewhql-218

How reproducible:
randomly, not 100%(1/15)

Steps to Reproduce:
1. python3 ConfigTest.py --testcase=block_during_io.iozone_stress.data_disks.send_shell.with_reboot --guestname=Win10 --platform=i386 --clone=no --driveformat=virtio_scsi --machines=q35 --customsparams="cdrom_virtio = isos/windows/virtio-win-prewhql-0.1-218.iso\nnum_queues = 8" --vcpu=8 --mem=4096

2. qemu command line:

3. format data disk and run iozone test on the disk:
D:\Iozone\iozone -azR -r 64k -n 1G -g 4G -M -i 0 -i 1 -I -f E:\testfile

Actual results:
BSOD

Expected results:
Passed
