[Xen-devel] RE: Why do I get a blue screen when do chkdsk operation on GPL Windows PV Driver DomU?

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

Thanks for that - I can reproduce this easily by running a couple of
chkdsk's as you say. I must be leaking gref's somewhere -
/var/log/xen/qemu-dm-<domuname>.log contains lots of "XenPCI No free
grant refs".

>From memory, chkdsk doesn't align its buffers the way blkback wants them
aligned so I have to double buffer them... that code path isn't used
particularly often so hopefully the problem lies there!
