Hi, don't expect that the kraxelpatch-3 for 2.4.22 will fit for 2.4.21. There was a patch for 2.4.21-rc4 and for me it worked last on 2.4.21-ac4. I think it was reported to produce errors on the 2.4.21 shipped with mdk 9.1. Looks like you have to get a new kernel from kernel.org and then, why not take the 2.4.22 with latest features? (If you have reasons to stay on 2.4.21 I can send you the old patch.) Hermann --
