Default Bug#518182: linux-2.6: Error with e1000 e1000_clean_tx_irq: Detected Tx Unit Hang

Package: linux-2.6
Version: 23
Severity: normal

I have a problem with the e1000 driver. The network card is not working correctly.
It looks like the problem shows only up with more then 4GB Memory. I have the same behavier with
an etch system under xen. On that system the card is working if I truncate memory to 4GB


Here are some information:
