Description Min Deng 2012-12-28 02:16:28 UTC

Description of problem:
  After guest does S3 and disables driver from device manager,and then shutdown the guest.Finally,the guest got BSOD(9f) issue.

Version-Release number of selected component (if applicable):
virtio-win-prewhql-0.1-49
How reproducible:
4 times 4 failed

Steps to Reproduce:
1./usr/libexec/qemu-kvm -m 2G -smp 2 -cpu cpu64-rhel6,+x2apic,family=0xf -usb -device usb-tablet -device virtio-scsi-pci,id=scsi0 -drive file=win7-32-clean.raw,format=raw,if=none,id=drive-virtio0,cache=writethrough,werror=stop,rerror=stop -device ide-drive,drive=drive-virtio0,id=virtio-blk-pci0,bootindex=2 -netdev tap,sndbuf=0,id=hostnet0,script=/etc/qemu-ifup,downscript=no -device e1000,netdev=hostnet0,mac=00:52:26:27:51:c6 -uuid e556eb83-f793-48e2-9661-b0f17499834d -no-kvm-pit-reinjection -chardev socket,id=111a,path=/tmp/monitor-win7-64-scsi,server,nowait -mon chardev=111a,mode=readline -chardev socket,id=seabios_debug,path=/tmp/monitor-seabios,server,nowait -device isa-debugcon,iobase=0x402,chardev=seabios_debug -device virtio-scsi-pci,id=scsi4 -drive file=disk4.raw,if=none,format=raw,cache=none,id=drive-virtio-data4,werror=stop,rerror=stop -device scsi-hd,bus=scsi4.0,id=virtio-data4,drive=drive-virtio-data4,serial=dsik44,lun=4 -drive file=/mnt/add30.qcow2,if=none,format=qcow2,cache=none,id=drive-virtio-data5,werror=stop,rerror=stop -device scsi-hd,bus=scsi4.0,id=virtio-data5,drive=drive-virtio-data5,serial=dsik44,lun=5 -M rhel6.4.0 -monitor stdio -qmp tcp:0:4444,server,nowait -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -spice port=5931,disable-ticketing -vga qxl -rtc base=localtime,clock=host,driftfix=slew
2.do s3 and resume guest
3.go to device manager and disable the driver
4.and then shutdown the guest  
Actual results:
The guest got BSOD issues
Expected results:
The guest works well even if the driver is disabling.

Comment 5 dawu 2012-12-28 05:43:11 UTC

This BSOD looks more probably caused by bug  https://bugzilla.redhat.com/show_bug.cgi?id=846912, since disable or enable scsi driver will stuck after S3/S4,if you reboot or shutdown guest at this time, this device will be blocking an Irp for too long a time and finally BSOD with 9f code.

I have tried this on win2k8-64, driver disable stuck after S3,and I reboot guest,BSOD happened.

If something wrong, please correct me, thanks!

Best Regards,
Dawn
