Using Compact Flash

I've got an ext3 formatted Compact Flash on a Cyclone II Eval Board.

At the Nios Wiki

http://nioswiki.com/operatingsystems/uclinux/compactflash

It tells you to select the

[*] Generic Platform

When I select this I get the following "make" error(s):

***************************************************

IF I SELECT:

[*] Altera SOPC Builder CompactFlash support (Experimental)

I successfully compile.

So, a few questions:

1. WHY CAN'T I COMPILE WITH THE "Generic Platform" selected

2. Is the "Altera Sopc Builder CompactFlash support" stable ?

The reason I ask this is because I was monitoring the writing to the CF and my interrupt of the data coming into my board and it appears that the IRQs are getting TURNED OFF for up to 13 milliseconds some times !!!

So, question

3. Does the "Altera SOPC Builder CompactFlash" driver TURN OFF INTERRUPTS ?

Thanks in advance
