Comment (by hunnia1):

 As I wrote disabling SMP will make AHCI/Haiku almost work except it will
 not see sda.
 So I went into debug mode with screen output and SMP disabled, to get some
 photos. At the end of the sequence sda was seen.
 Booted from the hard drive (sda) with smp disable, screen output and
 automatic paging.
 Haiku booted from the hard drive and worked perfectly.
 Tried it again witout the screen output and it failed. (Could not find
 root file system, which is obvious since sda not found.) Went back to
 screen logging and it worked again.
   Obviously there is something timing related. Race condition?
