Hi,
After a while (most recently 4 days) I am seeing the following in my logs:
Mar 13 15:36:45 xenserver kernel: NETDEV WATCHDOG: peth0: transmit timed out
This message will repeat every half hour or so until the dom0 is
rebooted. During that time the ethernet device and the domUs bridged
to it lose their network connectivity. I am not aware of any
particularly high network traffic or machine activity that coincides
with this.
Googling turned up the attached messages, but no responses. Any
suggestions would be greatly appreciated.
I am running xen 3.2 with the stock xen 2.6.18 kernel, both built from
source, on Debian Etch. The NIC in question is a D-Link System Inc
DGE-530T Gigabit Ethernet Adapter (rev 11) using the skge driver and
attached to a gigabit switch. Two identical NICs are passed to a domU
and are working without any problems.
