RE: [Xen-devel] system crashing while testing GPLPV drivers

I'm at home and the server is at work, so I have it set to automatically
reboot. There is nothing in any logs after the reboot.
I have found that if I pass a zero length network tx buffer, I get a
'BUG: warning" of:
BUG: warning at
arch/x86_64/kernel/../../i386/kernel/pci-dma-xen.c:364/dma_map_single()
Call Trace:
<IRQ> [<ffffffff8026bfa0>] dma_map_single+0x4f/0x1a7
[<ffffffff880b2ab9>] :tg3:tg3_start_xmit_dma_bug+0x449/0x7d9
[<ffffffff803bc759>] __qdisc_run+0x102/0x1c8
[<ffffffff80230964>] dev_queue_xmit+0x1f1/0x30d
[<ffffffff882a3f04>] :bridge:br_dev_queue_push_xmit+0x18b/0x1b2
The line in question is just a warn on mapping a dma buffer of length
zero.
I suspect that the actual crash is going to be something similar.
