I set my IntMode to 1 for both adapters due to bug 360. After 24 hours both adapters die under 50% load.
First it was ASPM on the 82574L that was found to have a hardware errata.
Then it is found that the same chip can't handle MSI-X.
Now I'm getting random "Hardware Unit Hang" messages.
This chip is a failure from the fab and Intel is still selling this chip today. A case could be made to blacklist this chip from the kernel since it has so many hardware bugs. None of my other Intel NICs, or competitors chips, have even one outstanding issue.
I'm attaching a screenshot of the hang since the error caused a complete lock up of the server and caused my RAID 5 to start a rebuild when I hard reset it.
I'm wondering what network card I want to replace the two defective 82574Ls as I have had enough with the constant problems of this one chip model. My desktops or laptops can stay up for weeks but my /server/ cannot last more than 24 hours.
Distro: Fedora 17 x86_64
Motherboard: Supermicro X8SIL-F BIOS 1.2a
I'm using the in-kernel driver.
