I Cc this message to the ata_piix maintainer, the debian bug tracking system for debian-installer (since it affects installation) as well as the linux-ide mailinglist (as requested in the ata_piix source) and the debian-boot mailinglist (though it should get a report from the BTS). If you think any of these are inappropriate, please let me know and remove them from replies please. I just experienced a problem with a Dell server which is using combined mode to provide a PATA port for its CD-ROM and an SATA port for its HD. The problem I experienced is as follows: the ata_piix driver detects PATA and SATA in combined mode (which does seem correct as far as I can tell). However, only the HD is detected/registered in the kernel while the CD-ROM remains undetected/unregistered. I therefore can't install using the default settings of debian-installer rc3 (netinst CD tested, other still untested, but since it's a kernel issue, I doubt they would make a difference. I was able to work around this issue by _not_ loading the ata_piix module at first, but load the generic ide driver module instead. Of course, that module doesn't detect the SATA part, so I would be able to access the CD-ROM but not the HD. However, loading ata_piix _after_ the generic IDE driver notes that the first port is busy (PATA, used by ide_generic) and only initializes the SATA part. This makes it possible to access both SATA (HD) and PATA (CD). If anyone wants access to the machine in question, I guess I could arrange both root and serial console access to it for a limited time. Will have to check with my boss though. Tell me if you would need that. regards, Sven PS: Please Cc me in answers unless you also send a copy to the debian-boot mailinglist (which I read).
