It doesn't matter what device I plug in. The devices work in other machines, in this machine running windows, and in this machine running linux with EHCI disabled.

Aye, the devices work like a charm with UHCI only.

^^^ That is my current, minimal USB setup. As you can see, the only device is the keyboard that I am currently typing on. If I enable EHCI, the kernel won't boot! If I unplug the keyboard (and all other USB devices), it will boot, but will crash as soon as I plug it back in.

Umm, did you mean ACPI? If so, that is already disabled.
> What'd be ideal then is to build your kernel with CONFIG_USB_DEBUG
It is already built in.
The boot messages that I copied down were from a formerly-booting, suddenly-crashed kernel with CONFIG_USB_DEBUG turned on.
> and use some console other than X11 so you can collect more information.
X had not come up by the time the kernel crashed. (Neither had the partitions mounted, or anything else that normally happens after EHCI loads.)

The boot-time text console reflects no fatal errors or warnings.
> Don't use 2.4.21 EHCI; use at least 2.4.22-pre1.
This problem also occurs with 2.6.0-test2. However, I will download 2.4.22-whateverisnewest overnight tonight.
