With "CPU C State" and "Spread spectrum" turned off after 47 hours I got: NETDEV WATCHDOG: eth1 (igb): transmit timed out Modules linked in: ... Call Trace: ... Let summarize: - None of kernel (29, 30) and driver combinations solved the problem - None of BIOS options helped - I've figured out that when TX Unit Hang on 2 configured ports, Loopback test fails on 2 unconfigured/used ports also - When the NIC stops working, rest of the system feels Ok So the problem localized a bit, but the source of the problem it's not clear. Is it hardware related or software... Also system is in use by ~300 customers, so more downtime that we already have is not desireable. Server has 2 onboard NICs with one of which we have had similar problem, and PCI-e Quad port NIC. We can still live with 2 NICs, so one of the options for further testing I see is to go back using onboard NICs and put PCI-e Quad port NIC to another server I support and do a loop back (Port1<-> Port2, Port3<->Port4) stress test, but there is 2.6.26 kernel (changing not an option). Let me know what you think and what are other options of further testing. I'm going to try 2.6.32 before switching NIC to another server. I Did not do this before because there was issues backporting it to Lenny. -- Покотиленко Костик <[email protected]> ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
