[Xen-devel] network (irq?) problems in unstable

[Gerd Knorr <kraxel@xxxxxxx>]

  Hi,

With xen unstable I have the problem that the network stops
working after a while.  Heavy network traffic seems to make it
more likely, it triggers almost every time I try to untar a
kernel source tree, where the tarball comes from a NFS-mounted
volume.

The network card doesn't receive interrupts any more according
to /proc/interrupts.  It works fine in native linux and also
with xen 2.0.  It's a tulip card.  Anyone has an idea what this
might be or where to look?
