13:46:20 I think so 13:46:52 ok, I added piix to /etc/modules, and that was better 13:47:03 at least on last reboot, now it won't work again :( 13:47:12 I'll try a new initrd image 13:47:50 i'll to 13:47:55 too 13:49:00 hrmm.. seems only /etc/hdparm.conf doesn't work 13:49:36 alex_joni: wich kernel ?

14:58:55 if you switch to initramfs-tools this would work first time, but that requires you to install udev, you can work (maybe) around this bug in yaird by reading the bug report and following the instructions in there (possibly substituting your ide chipset for whichever they are fixing in the bug) 15:00:08 15:50 < dpkg> #345374:N[yaird] yaird: Cannot turn DMA support for ide devices on; Fri, 30 Dec 2005 23:33:01 UTC 15:00:18 looking .. 15:03:38 I tried to add sis5513 (my chipset) in /etc/mkinitrd/modules and rebuild with mkinitrd -o /boot/initrd.img-2.6.14-2-686 but didnt work 15:03:56 lets try yaird 15:08:03 yaird?
