I have two different ethernet cards that exhibit issues on this system. An msk PCIe based card, and a PCI em based card... With MSI the msk card produced regular: msk1: watchdog timeout (missed Tx interrupts) -- recovering But was usable enough to push ~110meg/sec out. When I was watching an HD program streamed over http, there were regular hickups ever few minutes, which I figured was due to the above messages (though none appeared while watching), so I decided to switch back to my em based card, and w/ MSI the card is practically useless. I get: Apr 21 22:13:09 carbon kernel: em0: watchdog timeout -- resetting Apr 21 22:13:09 carbon kernel: em0: link state changed to DOWN Apr 21 22:13:12 carbon kernel: em0: link state changed to UP Apr 21 22:14:19 carbon kernel: em0: watchdog timeout -- resetting Apr 21 22:14:19 carbon kernel: em0: link state changed to DOWN Which ends up making things a bit difficult to pass usable traffic over the interface. After disabling MSI w/: hw.pci.enable_msi=0 in /boot/laoder.conf, things are now working again w/ em0. I have also switched back to msk1, and don't seem to be seing the watchdog timeouts that I was previously seeing.. Attached are pciconf -lv and dmesg from the box. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." --LwW0XdcUbUexiWVK Content-Type: text/plain;
