So you can't setup correcty some WC (Write Combining Areas). A simple script could workaround that by unsetting the "Write Back" ones and adding some WC. After that, performances are back, WC accesses are ok :) -- Erwan Velu Linux Cluster Distribution Project Manager Mandrakesoft 43 rue d'aboukir 75002 Paris Phone Number : +33 (0) 1 40 41 17 94 Fax Number : +33 (0) 1 40 41 92 00 OpenPGP key : http://www.mandrakesecure.net/cks/
