[Xen-devel] Blue screen when running 'xl block-detach' with GPLPV 0.11.0.372

[Fernando Luiz Chaves Xavier Matos <fernando@xxxxxxxxxxxxxx>]

Hi all,

I'm getting a BSOD when trying to detach a physical disk in Windows 7 SP1 32-bit guest.

It's a USB hard drive, attached using 'xl block-attach win7 phy:/dev/sdb,xvdb,rw' .

Using GPLPV 0.11.0.372 (gifted by James Harper).

The above command works, I can access the data normally, but to safely detach the drive, I must power off the guest and then power up again.

To trigger the BSOD, I run 'xl block-detach win7 <driveid>'

NOTE: I vaguely remember running this command successfully using the .356 version.

I have captured some info:
