[Xen-devel] xen-netfront: txqueues in a frozen state, no packets in the softqueue

Stefano,

   after a few days running traffic, we are seeing that one of the
linux netdevice txqueues has gone into a frozen state and any packet
that you give from there onwards is always queued to a softqueue and
is never put into the xen-netfront txqueue...

it also looks like xen-netfront is not registering a timeout callback
and this may lead to a crash if the callback ever gets invoked.

do you happen to know if this has been seen before and if there was a
fix for it?

we are currently running with linux-3.0.9.

Thank you!
-Alessandro-
