    SubjectOops on module insertion of 3c509/3c95x
    From
    Date
    This is a problem in 2.6.0-test10 and now tested with 2.6-test11-bk8 
    aswell which shows itself as I accidently
    tried to modprobe the wrong module (3c509) for my NIC which is:
    00:0d.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74)
    And after it modprobed 3c59x.
    This does NOT seem to happen with other modules, nor any other module
    in the 3cxxx series other than 3c509. This happens with pci=noacpi
    aswell.

    The impact of this is that the module's used counter "starts" at 1,
    which makes it impossible (ok, maybe with force) to unload it.
    (I cut the oops out of dmesg if anyone wonders.)
