Description of problem:

Emulate one fault disk, it will delay IO about 5 minutes.

Pass-through the disk to vm and boot it. The vm boot slowly.

The disk can be found in disk management after boot.

Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux release 9.0 Beta (Plow)
5.14.0-1.7.1.el9.x86_64
qemu-kvm-6.1.0-8.el9.x86_64
seabios-bin-1.14.0-6.el9.noarch
edk2-ovmf-20210527gite1999b264f1f-6.el9.noarch
virtio-win-prewhql-0.1-214.iso

(qemu-kvm-6.0.0-13.el9_b.5.x86_64 same result)

How reproducible:
100%

Steps to Reproduce:
1. emulate fault disk

1.1 create scsi_debug disk ==>/dev/sdb
modprobe scsi_debug dev_size_mb=128

1.2 create dm disk with fault sector ==> /dev/mapper/baddisk

dmsetup create baddisk << EOF
0 160000 linear /dev/sdd 0
160000 5 delay /dev/sdd 160000 0 /dev/sdd 160000 300000
160005 80000 linear /dev/sdd 160005
EOF

1.3 export the dm disk
(workspace) root@dell-per440-07 /home/vbugs $ targetcli ls
o- / ..................................................................... [...]
o- backstores .......................................................... [...]

1.4 attach the iscsi disk ==> sde

lsblk:
sdd 8:48 0 128M 0 disk
--baddisk 253:3 0 117.2M 0 dm
sde 8:64 0 117.2M 0 disk

2.pass-through the disk and boot it

3.wait for the guest boot,the check the disk
wmic diskdrive get index
or disk managerment.

Actual results:
Not found the disk

Expected results:
The disk should exist and usable.

There is no issue on RHEL guest.
And RHEL guest boot fast.The fault disk looks like does not affect the boot.
