So if you were compiling this stuff all into the kernel (I guess it was like this before, i.e. w/ the 15sec delay), you would definately create a driver collision which potentially could lead to a race condition. But I guess you didn't expect that to happen: It sounds as if you were assuming that CONFIG_ATA_PIIX only configures SATA support. But since 2.6.19, there's a "#define ATA_ENABLE_PATA" in include/linux/libata.h. That leads to PIIX PATA support via the *same* ata_piix driver/module that is used for SATA support. > In other words: > > PATA PIIX built-in it was two times with the old statically compiled version, once via old IDE layer, once via libata. > SATA PIIX as module that's only libata, so no problems with those devices. > No delay. /dev/sda continues to be /dev/sda. Same for /dev/hda But you need an initrd. Currently it's still experimental, but I would suggest at least trying to use libata for all devices. You won't be able to use the old IDE devices anymore in that case, so make sure that you have SCSI CDROM and SCSI generic support in order to make use of your DVD drive. -hwh -- gentoo-user@gentoo.org mailing list
