[Xen-users] DRIVER_IRQL_NOT_LESS_OR_EQUAL by xennet.sys, Server 2008 x64

[Mike Williams <mike@xxxxxxxxxxx>]

Hey guys,

I'm trying to get a gentoo dom0 running on some new Nehalem boxes.
Our dozen or so existing servers run a xenified 2.6.21, but we can't get the 
new Intel network chipset working with it.
So, I'm giving a pv_ops dom0 from xen-tip/master a go, and Xen 3.4.1 to go 
with it. rebase/master is a bit too bleeding edge for me. So far, it's working 
great.

Along with this, and the reason for the email, I need to get a 2008 Server x64 
install going on one of these Nehalem servers.
After installing gplpv_fre_wlh_AMD64_0.10.0.86.msi, following a "workaround" 
(http://lists.xensource.com/archives/html/xen-users/2009-05/msg00533.html, no 
"new disk installed" prompt however) as soon as I do any network stuff (web 
browsing, windows update, etc) it BSODs with DRIVER_IRQL_NOT_LESS_OR_EQUAL and 
restarts immediately, before being able to display anything.
Many attempts later I just caught the driver that "caused" the crash, 
xennet.sys. Which kinda makes sense, seeing as it's using the network that 
crashes it.
Boot NOGPLPV and it's perfectly fine.
I've done this now on two different installs, the second was completely 
updated, including SP2, taking several trips through windows updates, before 
gplpv was installed.
The network is DHCP and stateless IPv6 autoconfigured, and 2008 gets both 
addresses just fine.
Typically, I haven't seen anyone else seeing this problem. Am I the only one?

I have no particular compulsion to running xen-tip/master if that's the reason 
for the crash. The kernel just has to have support for the Intel 82576 NIC :)
Being compilable by GCC 3.4.6 would be a bonus too (pv_ops 2.6.30+ aren't).

Thanks
