So, the Jmicron stuff is still not working... It starts with the :
PCI: Device 0000:02:00.0 not available because of resource collisions
ahci: probe of 0000:02:00.0 failed with error -22

and then it fails to detect any kind of devices I have...

Robert, based on what you wrote, I have a few questions :
 - Should I activate CONFIG_SATA_SIL and/or CONFIG_SATA_SIL24 for the
   ata2 timeout,
 - If I set CONFIG_IDE=n, this will remove support for :
   . Floppy,
   . Scsi -> USB keys.
   or am I missing something ?

Regards,
Paul
