The cs5535 ide driver doesn't seem to be able to recognize the Karl> newer CS5536 controller for IDE. The IDE interface of the Geode CS5536 companion chip is a completely different beast. It's a more or less standard AMD 8111 PCI IDE device with slightly different timings. There's a dedicated driver called pata_cs5536.c (CONFIG_PATA_CS5536). The driver was developed on a Soekris net5501. To my knowledge it's working fine on ALIX boards. If that's not the case there may be a problem with the ALIX BIOS VSA PCI config space emulation. In that case you can load the driver with msr=1 to force it to program the IDE function using machine specific registers instead of relying on PCI. Let me know how it goes. -- Martin K.
