    Subject[OOPS][RTL8180] kernel panic with rtl8180 driver.

    I am trying to use rtl8180 driver version 1.3 for gcc 3.x
    Driver loads and inits successfully, and when I do iwpriv wlan0 enable
    it starts to work (prints messages about joining BSS, Roaming etc..),
    but after a few second (apparently after some Rx) I get the attached
    kernel panic. I am using vanilla 2.4.22 kernel with all debug options
    compiled in so looks like a memory allocation problem is being caught


    ksymoops 2.4.8 on i686 2.4.22. Options used
    -V (default)
    -k /proc/ksyms (default)
    -l /proc/modules (default)
    -o /lib/modules/2.4.22/ (default)
    -m /boot/ (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.
