[Xen-devel] Xen bug or sky2 device driver bug?

[Jae-Wan Jang <jwjang@xxxxxxxxxxxxxxxxxx>]

Hello,

I'm using ASUS P5WD2-E Premium mother board.
It has two Marvell Yukon II gigabit Ethernet and sky2 device driver is
used for them.

When domU receives lots of lots of packets (about 10Kb each),
dom0 crashes.
Unfortunately, my machine doesn't have serial port, I can't capture all
the oops messages.
Following is backtrace of the oops messages.

When domU receives lots of packets from other physical machine, kernel
panic occurs.

Backtrace

br_handle_frame
br_nf_pre_routing_finish
br_nf_pre_routing
nf_iterate
nf_hook_slow
br_handle_frame
netif_receive_skb
sky2_poll
net_rx_action
__do_softirq
irq_exit
do_IRQ
evtchn_do_upcall
hypervisor_callback
xen_idle
cpu_idle
rest_init
start_kernel
0xc010006f

Is it bug of Xen or sky2 device?

Thanks in advance.
