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.
