This sounds similar to problems reported on the 6500, you may want to try modifying de4x5.c with the attached patch. This just implements the fix that benh described a few months ago. To use, cd linux/drivers/net and then: patch -p0 < /path/to/patch/de4x5.patch Hopefully, this will fix your problems. --------------------------------------------------------------------------- | Nathan Ingersoll | Computer Science/Mathematics | | mailto: [EMAIL PROTECTED] | University of Minnesota-Duluth | | http://umn.edu/~ningerso | http://www.d.umn.edu | ---------------------------------------------------------------------------
