    Subject2.6.9-rc4-mm1 : oops when rmmod uhci_hcd [was: 2.6.9-rc3-mm2 : oops...]
    Hello,

    I posted the following bug to linux-usb-devel, and I did not receive
    any reply.

    As the problem still occurs with 2.6.9-rc4-mm1
    (optimize-profile-path-slightly.patch reverted), I decided to post
    it again.

    I cc Greg KH because he provides a fix for pci_register_driver and
    this oops is (indirectly) triggered by pci_unregister_driver (maybe
    these two things are related, just a guess...).

    regards
    ~~

    ksymoops 2.4.9 on i686 2.6.9-rc3-mm2. Options used
    -V (default)
    -k /proc/ksyms (default)

    Warning: You did not tell me where to find symbol information. I will
    assume that the log matches the kernel and modules that are running
    right now and I'll use the default options above for symbol resolution.
    If the current kernel and/or modules do not match the log, you can get
    more accurate output by telling me the kernel version and where to find
    map, modules, ksyms etc. ksymoops -h explains the options.

    Error (regular_file): read_ksyms stat /proc/ksyms failed
    No modules in ksyms, skipping objects
    No ksyms, skipping lsmod

    This architecture has variable length instructions, decoding before eip
