Hi,
leider habe ich keine Lösung zu meinem Problem im Netz finden können:
bonding (mode unabhängig) löst RX errors aus.
Dies geschieht erst seit einer neueren Kernel Version,
leider kann ich die letztfunktionierende Version nicht mehr einsehen.
Einen Workaround im Netz habe ich zu ähnlichen Themen finden können:
modprobe bnx2 disable_msi=1 && service network restart
Jedoch zeigte dies keine Wirkung auf unseren Systemen: Dell PE 1950 III
Hardware wurde bereits komplett gegen äquivalente Komponente getauscht, ohne Wirkung.
Das Problem tritt erst unter Verwendung des bonding stacks auf und kann auch mit einem kernel > 3.x nicht behoben werden.
Es muss mit dem bnx2 Modul zu tun haben.
Vielen Dank vorab für Ratschläge & Hilfe!
