Hello again:

Going up and down the kernel options I found

[*]   IGNORE word93 Validation BITS

Which help says:

CONFIG_IDEDMA_IVB:                                                            
                                   ?                                          
                                                                           ?
  ? There are unclear terms in ATA-4 and ATA-5 standards how certain          
                                          ?
  ? hardware (an 80c ribbon) should be detected. Different interpretations

  ? of the standards have been released in hardware. This causes problems:    
                                          ?
  ? for example, a host with Ultra Mode 4 (or higher) will not run

  ? in that mode with an 80c ribbon.                                          
                                          ?
  ?                                                                           
                                          ?
  ? If you are experiencing compatibility or performance problems, you        
                                          ?
  ? MAY try to answering Y here. However, it does not necessarily solve       
                                          ?
  ? any of your problems, it could even cause more of them.                   
                                          ?
  ?                                                                           
                                          ?
  ? It is normally safe to answer Y; however, the default is N.


Well, I have compiled a new kernel with this option and no results for me.
