I couldn't find anything which indicate that the two devices are configured differently. Can you please try the followings? 1. pata_acpi is being loaded for live CD. It fails during initialization and detaches but it might as well be that one of the acpi calls are messing up the configuration. pata_acpi is blacklisted by default for !live installations but it seems kiwi didn't pick it up. Can you please exclude pata_acpi and see what happens? 2. If that doesn't help, can you please test x86_64 live CD too?

We pretty much have to load all matching drivers (sans blacklisted ones) in the order specified by modules.order which udev/modprobe does fine. This is for the following two reasons. * Some controllers can switch between two different modes of operation but the selection is made by the bios (ata_piix/ahci for intel ICHs). In this case, the initrd _should_ carry both drivers and load them both in case the user switched the mode. * Some controllers can't be fully matched using the pci device ID mechanism used for module selection. Different generations of HPT drivers share the same PCI IDs but need to use different drivers. Only the driver init function knows whether it can attach to the controller or not, so unless all the matching drivers are loaded, some controllers won't get detected properly. By having two separate initrds, we're again facing problems which were solved quite some time ago. Is there any way not to do this? Thanks. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The illegal requests are probably from recent iso9660 probe update. IIUC, new code may try to access sectors near the end of the recorded area which tend to fail with certain hardware. It could be that those errors are somehow scaring the firmware into slower operation (it's ATAPI after all, everything is possible). Jan, is there a way to suppress those probings near the end of the media so that we can determine whether those illegal request failures are relevant to the slower performance?

Tejun, the changes in probe code were in UDF, there are no changes to ISO9660 and a quick check of isofs_fill_super() seems to show that it reads blocks only at the beginning of the media.

Oops, right. Sorry about the confusion.

But the messages could actually come from UDF code if something tries to mount the CD first as UDF and after that as ISO9660. So how is the filesystem mounted?

Yeap, something is triggering those errors. Trying w/o udf sounds like a good idea. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However, the firmware feels that something is wrong and speed down (I don't think this is a common behavior, it might not even be an intended one).
