Thread-topic: GPLPV + 32-bit Win2003R2 + Xen-3.3 unstable
I'm using the GPLPV drivers 0.9.11 with excellent network speedup on a
64-bit Windows 2003 R2 VM.

When I try the same under a 32-bit Windows 2003 R2 VM, the VM locks up
at the first sign of network traffic; even a ping from an external
client will bring it down. Using xentop I can see 100% cpu utilization
for that VM, and the vnc console becomes unresponsive.

With 0.9.12-pre4, the VM can take ping traffic from an external client.
When I load it up with ttcp from that client, it locks up again with the
same symptoms.

Removing /gplpv from boot.ini and restoring the qemu NIC makes the
problem disappear.

My s/w config is

Xen-3.3.0 release, 64-bit
SLES10 SP2 Dom0, 64-bit
Windows Server 2003 R2 Enterprise with SP2, 32-bit
GPLPV 0.9.11 / 0.9.12-pre4

Any pointers will be appreciated.
