Fixed In Version: kernel-2.6.32-71.20.1.el6
Doc Type: Bug Fix
Doc Text:
Prior to this update, starting multiple Red Hat Enterprise Linux 5.5 64-bit guests with network adapters based on the 8168c chipset or the 8111c chipset triggered an rtl8169_interrupt hang due to a RxFIFO overflow. With this update, infinite loops in the IRQ (Interrupt Request) handler caused by RxFIFO overflows are prevented and the aforementioned hang no longer occurs.
