Hi,
I report a benchmark result of this week on IPF using
ia64/xen-unstable and ia64/linux-2.6.18-xen.
On DomVTi, a kernel panic occurred when xen-vnif.ko was loaded. I
attach the message.
The issue was fixed by reverting the following patch:
http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg/rev/c48f54365060
But I have no idea why it causes the panic.
We tested without it.
