"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); } -- Keir > 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.
