Description Linda Wang 2005-10-28 19:57:43 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050512 Red Hat/1.0.4-1.4.1 Firefox/1.0.4

Description of problem:
Turns out that kernel modules from our tree built against say U1 will not 
load against U2. (Same was the case for GA -> U1). The reason is that we 
sign our kernel modules, and the signature changes everytime the kernel is 
rebuilt. The reason that binary modules work, is that if a module isn't 
signed then it loads anyways. So out of tree modules work.

Version-Release number of selected component (if applicable):
kernel-2.6.9

How reproducible:
Always

Steps to Reproduce:
1.install the system with RHEL4 Updates
2.load a previous version of driver module
3.
  

Actual Results:  Turns out that kernel modules from our tree built against say U1 will not load against U2. 

Expected Results:  allow all signed modules to load but marking them with a 'U' so that we know they aren't from the same rpm.

fix issue

This patch attempts to make all non-rpm modules show up as U. this means that
modules from different kernels will load but will just be marked with a U.
patch as of yet untested.
