PROBLEM: 2.4.4 and in2000

[Peter Chiocchetti]

hello,

patching the kernel from 2.4.3 to 2.4.4 broke the in2000 scsi
lowlevel host adapter module. ksymoops output below.

thanks, peter chiocchetti

-------------------------------------------------------------------------

ksymoops 2.4.1 on i686 2.4.4.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.4/ (default)
     -m /usr/src/linux/System.map (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.

Warning (compare_maps): ksyms_base symbol __VERSIONED_SYMBOL(shmem_file_setup) not found in System.map.  Ignoring ksyms_base entry
