Comment 1 Warren Togami 2004-07-05 05:32:17 UTC

WONTFIX for the following reasons:
* You are using a custom build of kernel which we do not support.
* This is also evident in your enabled PREEMPT, which is not enabled
in the Fedora kernel.
* Your kernel has been tainted by nvidia's closed source binary-only
module.  Nobody in the Open Source community can support you since
source is not available.  You need to go to nvidia for support.
