           Summary: ALX driver unusable on new kernel
           Product: Backports project
           Version: unspecified
    Kernel Version: 3.7.0
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Compat-Drivers
        AssignedTo: backports@xxxxxxxxxxxxxxx
        ReportedBy: i@xxxxxxxxxxxx
        Regression: No


After upgraded to kernel 3.7, the ALX driver in compat-drivers nolonger
functions. Building is successful, but it is unable to load.

dmesg before kernel update, using compat-wireless 20121003:
Dec 12 12:12:09 lightning.hexchain.org kernel: alx 0000:03:00.0: DMA to 64-BIT
addresses

After kernel update, any version of compat-driver before 20121204 fails to
build.
