Kernel panics on 9-CURRENT

[Yury A. Buldakov]

Hi,

My 9-CURRENT XEN box periodically panics on intensive net load, for
example on doing csup ports. Previously I was using 8-STABLE, and kernel
panics too, but currently I can't provide a report for this.

On 9-CURRENT error is (standard XEN kernel configuration):
