Why do the phy register reads determine during the check for link call? When debugging link issues the phy state of at least the first 15 registers is critical information. Are you enabling auto-mask or auto-clear for MSI? when you read ICR does it clear the interrupt or if you re-read does it return the same value? > e1000e 0000:01:00.0: eth0: Detected Hardware Unit Hang: do you see a NETDEV_WATCHDOG (once?) in the log, what does ethtool -S say? This will happen if tx packets aren't cleaned up, and since you're getting interrupts you need to get a hold of the e1000_dump routine code from sourceforge and call it when you detect a hang (patches for a bunch of drivers are up there, in the patches section.) this will provide information about whether descriptors are being written back or not. > msi: are my prints in the msi handler to print icr value. > > At this point driver is able to read write registers from pcie card, > msi interrupts are coming, > Now I am not sure why would the link go down. > I have connected the ethernet cable to another pc so the link should > always be up. Is the other end experiencing a timeout/reset event too? ------------------------------------------------------------------------------ What happens now with your Lotus Notes apps - do you make another costly upgrade, or settle for being marooned without product support? Time to move off Lotus Notes and onto the cloud with Force.com, apps are easier to build, use, and manage than apps on traditional platforms.
