Bug Description

Binary package hint: linux-source-2.6.22

after 14 or 15 guests, a new guest boots and the network interface is created ok, but no packets seem to traverse it.

after booting the guest, the output of "xm dmesg" gives:

(XEN) mm.c:2605:d0 Could not find L1 PTE for address eec00000

and the guest kernel prints a "XENBUS Timeout connecting to device: device/vif/1 (state 6)" error.

This has been reported to the Xen folks who claim to have fixed it. Details and patch here:
