Is there any ide message in /var/log/messages ? I see you use hdparm to setup the drive/controller settings. I advise you to let the kernel autotune the transfer modes by itself. Could you send us : - the exact kernel version, - your kernel compilation config file, - any kernel parameters provided, - the content of /var/log/dmesg, - the output of `lspci -vvxxx`, - the ouput of `cat /proc/ide/sis` Best regards, -- Lionel Bouton - inet6 --------------------------------------------------------------------- o Siege social: 51, rue de Verdun - 92158 Suresnes / _ __ _ Acces Bureaux: 33 rue Benoit Malon - 92150 Suresnes / /\ /_ / /_ France \/ \/_ / /_/ Tel. +33 (0) 1 41 44 85 36 Inetsys S.A.
