Just to rule out a few things, try disabling the following options in your .config: CONFIG_IDE_TASK_IOCTL (IDE Taskfile Access) CONFIG_IDE_TASKFILE_IO (IDE Taskfile IO) CONFIG_TULIP_MWI (New bus configuration) CONFIG_TULIP_MMIO (Use PCI shared mem for NIC registers) CONFIG_TULIP_NAPI (Use NAPI RX polling) CONFIG_TULIP_NAPI_HW_MITIGATION (Use Interrupt Mitigation) Taskfile access is, afaict, needed only if you're doing disk forensics or such. The new taskfile IO code hung up on me a few times on Cobalt when I was initially testing some of Peter's 2.6.x patches, and as such, I haven't cut it on since then. Tulip, I don't recall which, but I *think* one of them also caused me some kind of an issue, I'm unsure if it was a hang or something else. In either case, I left them as is. See if turning those off does anything different. --Kumba -- "Such is oft the course of deeds that move the wheels of the world: small hands do them because they must, while the eyes of the great are elsewhere." --Elrond
