Re: E-IDE probing succeeds at first, then fails ...

You didn't enable support for your IDE chipset and so you are using
generic IDE support (which can fail quite easy if i.e. BIOS programmed
wrong settings).  The easiest way is to see which driver you do need is
to enable all drivers and see which one will claim your IDE controller. :)
