           Summary: driver "sunhme" experiences corrupt packets if machine
                    has more than 2GB of memory
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.22.17-0.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Network

Latest working kernel version: unknown
Earliest failing kernel version: unknown
Distribution: OpenSUSE 10.3 (also tested on vanilla kernel) - filed on Novell
bugzilla at https://bugzilla.novell.com/show_bug.cgi?id=376831


Hardware Environment:
System 1: Q6600 cpu, 4GB mem, Asus P5N32-E SLI Plus, Sun QFE card
System 2: Q6600 cpu, 4GB mem, MSI P35 NEO-F (P35), Sun QFE card

Software Environment: OpenSUSE 10.3, both SUSE & vanilla kernels

Problem Description:

Network interfaces on the QFE card experience corrupted packets when the
machine has more than 2GB of memory. The NIC can successfully obtain a DHCP
address from a server, but attempts to ping or ssh to the address give
unexpected results
