            Bug ID: 196944
           Summary: [bge] [ipmi] regression IPMI access disabled when bge
                    driver is loaded
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org

    vendor     = 'Broadcom Corporation'
    device     = 'NetXtreme BCM5721 Gigabit Ethernet PCI Express'
    class      = network
    subclass   = ethernet
    bar   [10] = type Memory, range 64, base 0xfe5f0000, size 65536, enabled


Until 9.1p4 (at least), hw.bge.allow_asf which was set to 1 by default allow 
cooperating with IPMI .

Under 10.1, on the same hardware, this does not work any more. hw.bge.allow_asf
is still set to 1 by default, but IPMI access is disabled when the driver is
loaded.

This looks like a regression between 9.1 and 10.1
