Hi, I have an AMD Geode GX w/ the CS5535 chip and a compact flash adapter on IDE0/hda. There is nothing attached to IDE1. Not sure if it is relevant, but I'm using a 128 MB SanDisk. A 512 MB SanDisk and a 128 MB SImpleTech CF behave the same. I am using an unmodified linux 2.6.19-rc5. There are two seperate issues here. 1. If I enable the cs5535-specifc IDE driver, Linux can't find the root file system. I haven't been able to get dmesg output for this problem, as the kernel panics. This isn't a new issue, but I've never bothered to report it because IDE works without this driver. (The attached files do not relate in any way to this issue.) 2. Without the cs5535-specific IDE driver, I'm getting some weird timeouts at boot time. All told, it takes ~40 seconds to init the IDE stuff. Attached is my config and the complete dmesg output. Here's a section of the attached log related to the IDE/ATA stuff: [ 18.131962] Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 [ 18.132057] ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx [ 18.132612] Probing IDE interface ide0...

If ata2 maps to IDE1, then there is not an IDE device connected to ata2. I have in the past altered the IDE code to skip the timeout/retry code, but I was hoping for a solution that didn't require me to alter the kernel code. Any suggestions? Thanks, Ben
