Re: Strange virtio(4) behavior on Linode

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  Following up on my own post, by porting the latest fixes to the scsipi sources and
the vioscsi driver with respect to probing discontiguous luns, I am now able to utilize all the
virtual disks I created for my virtual machine.  It would be nice if these fixes could be back
ported to NetBSD-9, but since I'm working with something newer than  that, I probably am not
going to be the one to do that.

-thanks
-Brian
