Anybody experience such network stall in your > tg3 in bridge network environment? You are running exactly the same kernels on both 3.3 and 3.4? Then there can be no netfront/back differences as you are running exactly the same drivers. Certain things are on by default in 3.4 which were not in 3.3. One such thing is MSI. You might try disabling CONFIG_PCI_MSI in your dom0 kernel config. It'll be listed as "Message Signaled Interrupts (MSI and MSI-X)" in the PCI section of the Linux config menus. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
