I get problem reports all the time, unfortunately, so far these have not been reproducible on the configurations and hardware I have. I am not denying there is a problem, but if I can't reproduce it, it takes a long time to fix. Your problem seems to be missed/lost interrupts. If you display the contents of /proc/interrupts (ie cat /proc/interrupts), it will show whether level (good), edge (bad) or MSI (good if hw works) are being used. Some workaround related things to try are: 1) Adding the module parameter "idle_timeout=10" will cause the driver to poll for status every 10ms. This is obviously a performance overhead but it can allow system to function. 2) Disabling MSI with either "pci=nomsi" on boot cmdline or by using module parameter "disable_msi=1". Message Signaled Interrupts are good, but it seems some chipsets don't work right. -- Stephen Hemminger <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
