"full queue wasn't stopped" should never be printed. If you can
reproduce this message then it is worth printing some more info at th
esame point -- for example, np->tx->req_prod, np->tx->resp_prod,
np->tx_resp_cons. This will let us see whether the ring is indeed full.
If the network stack/driver has got itself into a state wher eit can print
this message, I'm not surprised it hangs for a while.
e.g., add this where that message gets printed in netfront.c:
{
unsigned long flags;
local_irq_save(flags);
printk(KERN_ALERT "full=%d req_prod=%08x rsp_prod=%08x"
"rsp_cons=%08x\n", np->tx_full, np->tx->req_prod,
np->tx->resp_prod, np->tx_resp_cons);
local_irq_restore(flags);
}

I'm playing with nbd+raid1, and am finding that during a resync the network=
in xenU is dying and simply not sending packets anymore. At first I though=
t this was a bridging problem, but in xen0 I have removed the vif from the =
bridge and given it its own ip address, and given the eth interface in xenU=
a similar ip address, but no traffic is passing anymore.
After a while though, it seemed to come good again and I was able to add th=
e interface to the bridge again and it started working.
The only strange thing in the kernel logs was this in xenU:
eth0: full queue wasn't stopped!
but i'm not sure at what point this was logged though.
