  • Thread-topic: system crashing while testing GPLPV drivers

I am rewriting the TX path in the GPLPV drivers and in its current form
I am readily able to crash the system (eg Dom0 and everything else
running) from DomU.

xen is 3.3.1, linux is at most a week behind the 3.3.1 release date.

My Windows DomU boots up, fails to get an IP address (yes, the TX path
is broken), and then a short time later the system has rebooted.

I don't know exactly what is causing it, but I suspect that I'm handing
netback some badly formed buffers or something and causing a bug check
in Dom0.

James
