That's another bug. It doesn't correspond to your problems.

That's the real reason for the failure. Do you have IDE built as modules?
Basically, the kernel checks whether it can access the device at boot
time before mounting anything. For 2.6.11.4 this is not possible with
swap devices which depend on any modules loaded. Compile in every driver
needed to access your swap device.

Yes, see above.
